Through former industrial textile manufacturing spaces and the spectacular architecture of this Modernist building the museum shows the evolution of scientific and technological advances in Catalonia, paying special attention to their industrial application and their effect on society.

The Masia Freixa is a building inspired by Gaudi and built by architect Lluis Muncunill i Parellada between 1905 and 1910. It is built on the structure of an old textile mill owned by industrialist Josep Freixa, who later converted it into his family residence. Of interest are the rounded cross-sections and the use of the parabolic arch, which make the building one of the treasures of the city’s Modernist Heritage. The City Council bought the farm in 1959 and its gardens became the city’s first public park. Located right in the middle of the Parc Sant Jordi, at present it is home to city council offices and the Tourist Office.

The home of the former Bishopric of Egara, in the Churches of Sant Pere in Terrassa, is an exceptional architectural ensemble in Europe. Founded in the middle of the 5th century, La Seu d'Egara makes it possible to travel back in time to the end of the Roman Empire and the first centuries of Christianity. The precincts preserve some exceptional architectural and artistic items: Iberian and Roman remains, a funerary church (Sant Miquel), Egara Cathedral, etc. The Churches of Sant Pere and Santa Maria are also one of the finest Catalan Romanesque ensembles and host an excellent collection of 15th century Gothic altarpieces. Located in the Parc de Vallparadis, they offer visitors a culture and tourism centre equipped with videos which accompany the tour of fifteen centuries of history through the most distant roots of Christianity and European art and culture.

It was built at the beginning of the 19th century as a workshop and home for animportant manufacturer from Terrassa. Original mural paintings have been preserved from this period. Major refurbishment in 1911 converted the building into a model for middle-class housing in Terrassa in an eclectic style within the Modernist movement. Of particular importance are paintings by Alexandre de Riquer which are presently on display in the dining room. In the different rooms of this building, visitors appreciate collections of great interest such as the Salvans collection of Far Eastern art, paintings by Martinez Lozano, drawings by Mateu Avellaneda and the legacies of the writers Agusti Bartra and Ferran Canyameres
