Sofia was a Roman city called Serdica long before it was a capital, and the people who prayed here have changed many times since. In a few streets west of the Largo you can meet Jews, Catholics, Orthodox Christians and the arena crowds of Rome.
This short walk takes in five stops in about two hours. Three are places of worship you can step into, one is a government building you only look at, and the last is the Roman amphitheatre, where the walk ends among the oldest stones of all.
Sofia Synagogue
Start at Sofia Synagogue, opened in 1909 and designed by the Austrian architect Friedrich Grünanger. Its Moorish and Byzantine details are easy to spot from the street. Inside, an octagonal dome rises over the main hall, and a chandelier weighing 1.7 tonnes hangs beneath it. The building also holds the Jewish Museum of History.
St Joseph
A short stroll south brings you to St Joseph, the city's Catholic co-cathedral. The first church here was built from 1875 and was destroyed in the bombing of March 1944. The community then made do with a small hall for decades, and the new church was consecrated in May 2006. It stands on the old site, with a tall bell tower.
Church of St Petka of the Saddlers
Head east towards the big department store and go down into the underpass beside it. The small Church of St Petka of the Saddlers is sunk into the ground here, below today's street level. It is named for the saddlers who once worshipped here, and its walls carry murals from several centuries, the oldest from the 14th.
The Presidency
On the Largo, the pale Presidency is the building on the south side of the square. It went up in the 1950s as the seat of the Council of State, and today it is the office of the President of Bulgaria. Ceremonial guards stand at the entrance.
Amphitheatre of Serdica
Finish at the Amphitheatre of Serdica, a short way east on the south side of the boulevard. It was built in the 3rd and 4th centuries and could seat more than 20,000 people. It was found by accident in 2004 while a hotel was being built, and part of it now sits inside that hotel.
Roman arena, medieval chapel, rebuilt cathedral and synagogue sit within a few minutes of each other here. That crowding is the point: Serdica never stopped being rebuilt, and each faith left its mark on the same few streets.
