The Cathedral, also called Surp Asdvadzadzin (the Church of the Holy Mother of God), was built in 989 AD by King Smbat II. The building wasn't completed until 1001 AD. It had a domed basilica, but that structure collapsed in 1319 AD. The building contains pointed arches and clustered piers. to give it a Gothic style. The Cathedral was designed by the architect Trdat. It's one of the best preserved of the Ani churches.
The churches and fortification of Ani extend down into the deep gorge which runs next to the main center of the once great city.
