Megaron Gyzi, Cultural museum in Fira, Greece.

Megaron Gyzi Museum is a former mansion in Fira that now houses drawings, historical maps, and photographs of the island. The collection documents how Santorini changed and developed across different periods.

The building was constructed in the 17th century and served as a family residence for many years. It survived the 1956 earthquake and remains one of the few examples of that architectural style still standing on the island.

The mansion belonged to the Gyzi family, whose name it carries, and its rooms are laid out as a Cycladic town house with vaulted ceilings and a walled courtyard. Displays of engravings, maps and photographs show the trades and daily routines of 18th- and 19th-century Fira.

The museum is located opposite the Catholic Cathedral, making it easy to find while walking through central Fira. It operates during the warm months, so plan your visit between May and October when the building is open to guests.

The museum holds a special collection of photographs by Vicentio Pintos taken between 1930 and 1956 that capture Fira before major transformations. These images are valuable because they show what the landscape looked like during a crucial period in the island's past.
