Constructed in the Neo-Byzantine style between 1876 and 1883, when the country was a part of the Russian Empire, the Nativity of Christ Cathedral in Riga is the largest Orthodox church in the city. It has undergone several transformations over the years, being used as a planetarium and a restaurant during the Soviet Era. However, it has since been fully restored as a church and now holds regular Orthodox services. It has also one of the biggest organs in Europe with 6,768 pipes.

Housed in a romantic Italian-built villa from 1890, the Naval Museum traces Bulgarian maritime history from the earliest Black Sea navigators of the 6th century BCE through to the Second World War and beyond. Inside, twelve halls across two floors cover naval battles, ship models, uniforms, navigational instruments, and lighthouse optics. The undisputed highlight is the Druzki, a torpedo boat that sank a Turkish cruiser during the First Balkan War of 1912. You can pay a small supplement to board it. In the grounds you'll find anchors, artillery, a submarine, and a helicopter slowly weathering the sea air.

The second largest square of Clermont-Ferrand, just after the one of Jaude, Place de la Victoire is located in the heart of the historic centre of the city. Besides the Cathedral of Our Lady of the Assumption, it is surrounded by notable buildings, including the former home of the famous philosopher Blaise Pascal. In the centre stands the statue of Urban II, the pope at the origin of the First Crusade. Today, it is a dynamic gathering place thanks to its several bars and restaurants.
