The most noteworthy of the Roman villas in the area is undoubtedly Els Ametllers.
Discovered in 1914 by Dr Ignasi Melé, it was one of the most important villas in the ancient Roman province of Tarraco. This is a classic example of a Roman Mediterranean farming establishment, where vineyards were tended and large quantities of wine were exported.
Bone and ivory styluses, ceramics, coins and brooches are on display in Tossa's Municipal Museum.
The Hospital of Sant Miquel was founded in 1773 at the final request of Tomàs Vidal Rei. This man was an outstanding local figure considered to be the precursor of the indianos, Spaniards who returned from the Americas after making their fortune.
Tomàs Vidal had travelled to both Puerto Rico and Guatemala long before King Charles the Third liberalized trade in 1765 by opening up Spanish ports to American ships.
On his return to Tossa, Vidal donated much of his American fortune to the construction of a charity hospital for the poor.
The large, rectangular 2-storey hospital is built around a cloister, with a side chapel dedicated to St Michael, patron saint of 18th century hospitals in Catalonia.
