Chiesa di Sant'Agostino

The cathedral of Teramo was built in the Romano-Gothic style between 1158 and 1176. The church was started in 1158, on the order of Bishop Guido II of Teramo, to house the relics of St. Berardo after the destruction of the ancient cathedral of Teramo, Santa Maria Aprutensis, in 1155. In 1331-1335 Bishop Niccolò degli Arcioni had extensively modified the building. The northern part was enlarged to the detriment of the three apses, which were removed. The new building was offset. In the 18th century, the church was modified to adapt it to the Baroque style. The columns and the six Romanesque bays were replaced by two domes, supported by pillars; the naves were lowered, the interior was decorated in stucco and two portals were opened on the sides of the main portal. In the 1930s, a restoration was carried out to restore the church to its original medieval appearance.

The church of Sant'Anna dei Pompetti, together with the neighbouring church of Santa Caterina, was originally part of the complex of the ancient cathedral of Santa Maria Aprutiensis from the 6th century. The building is made up of what has survived and been preserved from the old cathedral building.

The church of Saint Catherine was built around the 9th century. In 1803 the church was rebuilt in its most recent form. The church is a private chapel belonging to the local Castelli family and is only open to the faithful for a few days a year for the celebration of the triduums preceding 25 November.
