The Church of San Esteban, with its stylized tower, can be seen from almost anywhere in the town of Tapia. Neo-Gothic in style, it comprises three naves separated by pointed arches on pillars and covered by groin vaulting.
At the east end it has a square bell tower topped by a balustrade, where a huge stone statue of the Sacred Heart stands.
One of the people behind the building of the church, which commenced in 1896, was the Marquis of Casariego.
