Terrassa

These three churches were built close to the site of old Ègara to be the seat of the Ègara Diocese, which was founded around 450 CE and remained in existence until the 8th century. This episcopal complex follows the Byzantine model of antiquity, with two churches (Sant Pere and Santa Maria) and a mausoleum (Sant Miquel). After a long period of construction, the churches were finished in the then-current manner about the 11th and 12th centuries and in Romanesque style, on the site of the pre-Romanesque buildings of the Visigothic period. The church of Santa Maria contains outstanding works of art, and there are murals dating from the Romanesque period to the Gothic. There is also an altar stone dating from the 10th century and medieval and Romanesque tombstones (one of which documents the name of the Roman town of Egara). In the transept there are three Gothic altarpieces:
Santa Maria (Saint Mary) the old Cathedral
Sant Pere (Saint Peter)
Sant Miquel (Saint Michael).

mNACTEC runs several museums across Catalonia, this one specialises on textiles. The aim of the museum is to provide a comprehensive overview of the history of knowledge and technology in Catalonia, and the process of industrialisation. It starts with the Neolithic revolution, shows power generation techniques with waterwheels, electricity and turbine drives and solar technology.

The museum's extensive collection, with over 20,000 representative pieces of textile history from around the world, is presented in different temporary monographic exhibitions, lasting between ten and twelve months in the Modernisme area on the first floor, and two to three years on the second floor.
