The Casa da Troia Museum is located in the heart of Santiago de Compostela old town, very close to the church of San Martiño Pinario the Cathedral. The museum re-creates the environment and decoration of a students' dormitory and Santiago's university life of late 19th century. The recreation is based in the novel by Alejandro Pérez Lugín “La Casa de la Troya” (House of the Troy). From 1886 to 1906 the Casa da Troia was a students' dormitory. The 90s restoration reconfigured the rooms and chambers just like the guesthouse that appears in the novel. 

Following the reception in the ground floor, the first floor reproduces the former hall and study area (apart from being the rehearsal room for the tuna of Santiago at some point) and the respect hall, the space for receiving the students' families. In the second floor the visitor will see the bedroom. The kitchen is located in attic the highest part of the house, to use as much as possible the natural light and ease the smoke evacuation. 

In the basement and old stable (the visitor can see original downstairs), there are objects and souvenirs of the Tunas da Universidade de Santiago de Compostela from different years. All these pieces formed in the Tuna Museum, where the visitor can behold musical instruments, sashes, capes, trophies, photographs... 

The museum houses a historic library with works of Pérez Lugín, along with publications by related writers like Valle-Inclán, Camilo Bargiela, Manuel Casás, Enrique Labarta… and other books around Santiago's theme.
