The mausoleum Anthymos I is a funerary monument located in the courtyard of the Metropolitan Church of the city of Vidin. Here rest the remains of Metropolitan Preslav and Vidin, Chairman and founder of the Grand national Assembly and of the first Bulgarian Exarch, who lived in the period from 1812 to 1888.

The mausoleum was built by the architect Ilya Popov in 1934. Stone building, reminiscent of a Church at the base has a square shape. The building is crowned by a low octagonal prism, which forms the basis for a small cylindrical tower with Windows. The last are made of white stone and topped by a dome. Entrance to the tomb is decorated in the form of decorative arches, standing on four decorated capitals of the columns – two on each side. Above the arch is made in the form of a mosaic portrait Anthymos I.

Inside the walls of the mausoleum are decorated with paintings. In the middle of the room is a statue by the sculptor Ivan Doulova depicting seated Exarch. In the dungeon of the tomb is a sarcophagus with the remains of the Exarch.
