What is the name of the crypt that Gaudí designed for the Church of Colònia Güell?

The crypt Gaudí designed for the Church of Colònia Güell is called the Crypt of Colònia Güell.

It forms the completed lower portion of Gaudí’s larger, unfinished church project in Santa Coloma de Cervelló, near Barcelona. Count Eusebi Güell commissioned Gaudí to design a place of worship for the workers and residents of his company town.

Gaudí worked on the project from 1898, although construction did not begin until 1908. The crypt was built largely between 1908 and 1915 and was the only part of the planned church completed according to the original project. Its inclined columns, rough stonework and stained-glass windows integrate the building into the hillside.

The site is often confused with Gaudí’s better-known Barcelona works, such as the Sagrada Família or Park Güell. The crypt is especially important because Gaudí used it as an experimental laboratory for structural ideas later developed in the Sagrada Família.
