Museum of Natural History of the Academy of the Fisiocritici: curiosities and collections

Introduction

Siena is a city of timeless charm where art, history and tradition intertwine in every alley. Strolling through its medieval streets you are enchanted by the centuries‑old brick palaces, jewel‑like squares and panoramic views over the Tuscan hills. The entire historic centre is a UNESCO World Heritage site . Visiting Siena is like leafing through an open‑air history book: you wander among evocative piazzas, Gothic churches and authentic scents, from freshly baked bread to the spice stalls at the market . Every season offers unique emotions – from spring blossom to the Palio in summer, the golden autumn and the intimacy of winter .

Within this rich cultural setting there is an unmissable place for science enthusiasts: the Museum of Natural History of the Academy of the Fisiocritici. It is one of the oldest scientific museums in Tuscany, born out of more than two centuries of acquisitions and donations . Housed in a former Camaldolese monastery, the museum conserves extraordinary collections of natural and historical artefacts, period instruments and unusual objects in an exhibition that retains a 19th‑century atmosphere . The museum is organised into geology, zoology, anatomy and botany sections around a central cloister where “Nereo”, the 15‑metre‑long skeleton of a whale, hangs .

This in‑depth guide, structured as a series of questions and answers, will lead you through the Museum of Natural History of the Academy of the Fisiocritici, revealing its curiosities and most fascinating collections . It also presents Hotel Minerva as an ideal base for exploring Siena and provides practical tips on how to reach the museum (on foot, by public transport or by car) .

The Museum of Natural History: questions and answers

What is the Academy of the Fisiocritici and why does it have a museum in Siena?

The Academy of the Fisiocritici is a historic scientific institution founded in 1691 by Pirro Maria Gabbrielli, professor of medicine and botany . The term “Fisiocritici” literally means “judges of nature” and expresses the Academy’s mission: to study and judge natural phenomena through scientific observation . In the 18th century it became one of Europe’s most prestigious academies, counting among its members scientists such as Carl Linnaeus, Alessandro Volta and Louis Pasteur . From its foundation the Academy collected books, documents and scientific specimens. Alongside a rich historical archive and library, it created a museum of natural history open to the public .

The Museum of Natural History is thus an integral part of the Academy, fulfilling its mission of scientific dissemination . Since 1816 the museum has been housed in the former convent of Santa Mustiola, a 12th‑century building converted into an exhibition space . Visiting the museum means not only admiring valuable natural history collections but also breathing the atmosphere of an era when museums were born as cabinets of curiosities. The exhibits are displayed in original 19th‑century cases, preserving the charm of a “museum within the museum” . In short, the Academy and its museum represent a unique historical‑scientific heritage where past and present meet .

Why is Siena’s Museum of Natural History special?

Several factors make this museum special. First is its age and historical importance: it is one of the oldest scientific museums in Tuscany and Italy, with origins in the 18th century . The collections were formed over time through donations and acquisitions by scientists and collectors from all over the world , making the museum a treasure chest of curiosities. The fact that it is housed in a former medieval monastery adds fascination: the vaulted rooms and cloister with a 16th‑century well are part of the visitor experience . Walking among the wooden and glass cases is like stepping into the 19th century, when science was driven by the passion for discovery and collecting “natural wonders” .

Another distinctive feature is the period display. The museum preserves its original 19th‑century layout, with collections arranged in old wooden vitrines . This provides an atmosphere far removed from modern interactive layouts, but fascinating for those who love “old‑style” museums . The museum is called a “museum within the museum” because visitors see not only the specimens but also how they were presented to the public more than a century ago .

Finally, the museum is special because it reflects both local identity and a global vision. Many materials come from the Siena and Tuscan region—fossils, rocks and animals—offering a view of southern Tuscany’s natural history . At the same time there are exotic and international specimens—minerals from foreign mines, animals from other continents—testifying to the Academy’s scientific connections across Europe and the world . This heterogeneity, from local fossils to rare tropical specimens, makes the visit varied and interesting .

What sections and collections can be explored in the museum?

The museum’s exhibition is divided into four main sections dedicated to different branches of natural science :

Geology – rich collections of rocks, minerals and fossils. Many samples come from mines and deposits in southern Tuscany (Mount Amiata, the Siena area), but there are also specimens from other regions and countries . The minerals include metallurgical products from historic mines, while the fossils span the Carboniferous to the recent era, with emphasis on the Pliocene when Siena was covered by the sea . Curiosities include tufts of hair from a Siberian mammoth calf and three large megalodon shark teeth . The geology section also displays special collections such as the colourful “Terre di Siena” clays used as natural pigments, and samples of all 23 types of stone used to build Siena’s cathedral .
Zoology – a variety of skeletons and taxidermy animals from around the world . Visitors can observe tropical birds, fish and reptiles preserved in liquid, and mammals of various sizes. The most spectacular piece is the 15‑metre whale skeleton “Nereo” suspended in the central courtyard . Seeing this enormous cetacean up close is impressive and remains a highlight, especially for children .
Anatomy – perhaps the most unusual section, dedicated to human and comparative anatomy. It contains part of the scientific heritage of Paolo Mascagni (1755–1815), the great Sienese anatomist . Among the treasures on display is the first life‑size human anatomical atlas produced by Mascagni . The Francesco Spirito collection of petrified human organs shows body parts that were mineralised through a special process and preserved permanently . Another curiosity: Mascagni’s preparations demonstrate lymph vessels injected with mercury to make them visible—an ingenious technique used before modern contrast media .
Botany – the highlight is the Francesco Valenti‑Serini collection of terracotta mushrooms . Dozens of three‑dimensional models, hand‑modelled and painted in the 19th century, accurately reproduce various mushroom species and were used for study and teaching . Besides the mushrooms, this section includes historical herbaria of dried plants, a xylotheque (collection of wood samples) and a spermotheque (collection of seeds) , offering a glimpse of pre‑modern botanical sciences .

In addition to the main sections there are smaller collections, such as an archaeological section with Etruscan funerary urns displayed in a tomb‑like setting and a historic library with more than 36 000 rare scientific volumes . A summary table in the Italian article recaps the contents and curiosities of each section .

Which exhibits are the most curious and unusual?

Besides the “canonical” collections there are many curious items that catch visitors’ attention. They include:

Napoleon’s coconut shell – a half coconut said to have been used by Napoleon Bonaparte as a drinking cup during exile . Whether or not it really belonged to the emperor, this quirky relic embodies the “mirabilia” beloved in historical museums .
“Monsters” of nature – examples of biological anomalies such as two‑headed animal foetuses and skeletons with congenital deformities preserved in fluid. In the 19th century these attracted much scientific and popular interest . Today they may seem macabre but they reflect early scientists’ attention to every manifestation of nature .
Ancient scientific instruments – measuring devices and apparatus such as a 17th‑century pneumatic (vacuum) machine used for experiments on atmospheric pressure, and a large meridian line traced on the floor or wall to mark solar noon . These instruments are aesthetically appealing and tell of past scientific discoveries .
Fearsome exhibits – complete skeletons of exotic animals (crocodiles, big cats, raptors) and taxidermy animals in realistic poses . A large stuffed crocodile hangs from the ceiling, reminiscent of specimens once displayed in pharmacies or wunderkammern as symbols of faraway lands . There are also deep‑sea fish in jars and snakes preserved in alcohol .
Artistic and educational collections – drawings, watercolours and models once used by artists and naturalists for study . Hand‑illustrated plates of plants and animals and manuscripts of Sienese scientists are kept in the library and archives .

This mix of natural history and human history ensures that each display case holds a surprise. For families, finding these unusual objects can become a game—who finds Napoleon’s coconut first? .

How long does a visit take and who is it suitable for?

The length of your visit depends on your interests. To calmly see all sections and linger over the main exhibits, plan for around 1½ to 2 hours . Enthusiasts who enjoy reading labels may spend up to 2½ hours. A quicker visit with small children might last 45 minutes, focusing on highlights such as the whale skeleton, terracotta mushrooms and a few curiosities .

The museum appeals to a wide audience. It is ideal for natural science lovers, students of biology, geology, medicine and veterinary science, and those interested in museology . It is also perfect for families: children are fascinated by the taxidermy animals (like a plush zoo) and the giant whale skeleton . The museum runs workshops and treasure hunts for schools and families . Accessibility has been improved with lifts and ramps added in the 2000s , and digital supports (touchscreens, app, online catalogues) enrich the visit . In short, whether you are scholars, curious tourists or families seeking an educational activity in Siena, the museum will entertain you .

What are the opening hours and admission fees?

Opening times vary by season and day . Generally the museum is open mornings and part of the afternoon on weekdays, with longer hours on some days and afternoon opening on Saturdays; it is closed on Sundays. From April to October it is open Monday and Friday 9:00–19:00 (all day); Tuesday, Wednesday and Thursday 9:00–15:00; Saturday 14:00–19:00; closed on Sundays and holidays .

Where exactly is the museum and how do you get there?

The Museum of Natural History is located in the historic centre of Siena, at Piazzetta Silvio Gigli 2, near the church of Sant’Agostino and the University of Siena’s Botanical Garden . It lies about 400 m southeast of Siena’s cathedral (a 10‑minute walk) and at a similar distance from Piazza del Campo .

On foot – From Hotel Minerva or the northern part of the city, the museum can be reached by walking through the centre. From Via Garibaldi head towards Piazza del Campo via Banchi di Sopra and Corso; cross Piazza del Campo and continue to Sant’Agostino. The distance from the hotel is about 1.2 km, taking 15–20 minutes . The route involves some hills but offers picturesque views .

Public transport – Siena’s urban buses (Tiemme/Autolinee Toscane) connect different parts of the city. From Hotel Minerva you can reach Piazza Gramsci and take a bus towards Sant’Agostino or Porta Tufi. Lines such as the S10, S17, 0S7, S27 and 590 stop near Piazzetta Silvio Gigli . The bus ride from the centre takes 5–7 minutes . However, given the short walking distance, public transport saves little time unless it is raining or you have mobility issues .

By car – The museum is within the limited traffic zone (ZTL). Visitors cannot drive directly to the entrance without special permits .
