Building of the Holy Synod of the Bulgarian Orthodox Church

The building in not bad and you can take a glimpse at it from outside.

This is the Seat of the Synod.
In several of the autocephalous Eastern Orthodox churches and Eastern Catholic Churches, the patriarch or head bishop is elected by a group of bishops called the Holy Synod. For instance, the Holy Synod is a ruling body of the Georgian Orthodox and Apostolic Church.

In Oriental Orthodoxy the Holy Synod is the highest authority in the church[1] and it formulates the rules and regulations regarding matters of church organisation, faith, and order of service.
