The building underwent many repairs over the centuries. The largest were required because of earthquakes: in 790, under Empress Irene, and – after the great earthquake of 869 – under Basil I (r. 867–886). On 7 September 924 Tsar Simeon I of Bulgaria burned the complex, which was at once restored by Romanos I Lekapenos (r. 920–944). Three years later the son of Simeon, Peter was married to Maria, the niece of Lekapenos.
