Sofia City Province is Travelog's home for Sofia, anchored by Boyana Church, inscribed by UNESCO in 1979 under criteria (ii) and (iii), a building constructed in three distinct periods, the 10th, 13th, and 19th centuries, whose 1259 frescoes are protected by a strict, genuinely enforced 9-visitor limit at any one time.
