Chapel of Souls(Chapel of Santa Catarina)

The Church of the Holy Spirit, also known as the Chapel of the Souls, is located in the parish of Santo Ildefonso in Porto, Portugal. It is a well-known building on the shopping street of Calle Santa Catarina. Its exterior walls are famous for its blue tiles. These tiles were designed by Eduardo Light and depict the life stories of Saint Francis and Saint Catherine.

The chapel was built in the early days to commemorate Saint Catherine and is an old wooden structure. The existing building was built at the end of the 18th century and was rebuilt because the Brotherhood of the Scarred Souls of Saint Francis moved here. It was expanded and restored in 1801. The main facade of the church has a framed door with a round gable and a shield on the top. On the left is a two-story bell tower with an iron cross on the top. The interior is in neoclassical style, and the large painting "The Ascension of the Lord" by Joaquin Raphael hangs on the main altar. In addition, the stained glass windows created by the 19th-century painter Amandio Silva are also worth seeing.

Before 1929, the church's exterior walls were white stucco and not tiled. Today, these tiles have become its iconic feature and attract many tourists.
