The church of Alexander Nevsky was originally a small chapel built in 1896. Only few years (1896-1897) later it was reconstructed as a church by the design of Architect A. Krasovski. The central part of the church is covered by a high, tented roof in 'Moscow style', crowned by an onion dome. It also has other characteristic features of Russian Orthodox churches, and is renowned for its iconostasis. During colder months the church was used for services, and all year round as a venue for funerals.

The Cathedral of Saint Mary Major, often called Lisbon Cathedral or simply the Sé, is a Roman Catholic cathedral located in Lisbon, Portugal. The oldest church in the city, it is the seat of the Patriarchate of Lisbon. The cathedral has survived many earthquakes and has been modified, renovated and restored several times. It is nowadays a mix of different architectural styles.
The site where it stands was the principal mosque of Lisbon when it was an Arab settlement. The construction of the cathedral started around 1150, three years after the city was conquered from the Moors during the Second Crusade. Shortly after the victory the English knight Gilbert of Hastings was named bishop of the city of Lisbon.
One good reason to visit the Cathedral is to visit its charming cloisters located in the back. There are several tombs in the cathedral, the most notable of which is the beautifully sculpted tomb of Lopo Fernandes Pacheco and his wife.
