The Santa Ana Church is located in Casillas del Angel in the Puerto del Rosario Municipality, next to Los Llanos de la Concepción.

The church was built during the first half of the XVIII c.,it has undergone later extension works that have resulted in quite a large nave with a two-sided sloped roof. The presbytery is separated by stairs from the worshipers and has a four-sided sloped roof whereas the vestry is attached to the southern wall and connected to the church by a door leading to the presbytery. The church can be accessed by either of the two doors; one of them, with a Roman Arch, is located in the main façade. The main façade, one of the most impressive on the island, is made in black broadstone. The belfry has three bells.
