St. Alexander Nevsky Cathedral (Bulgarian: Храм-паметник "Свети Александър Невски", romanized: Hram-pametnik "Sveti Aleksandar Nevski") is a Bulgarian Orthodox cathedral in Sofia, the capital of Bulgaria. Built in the Neo-Byzantine style, it serves as the cathedral church of the Patriarch of Bulgaria and it is one of the largest Christian church buildings by volume in the world. It is one of Sofia's symbols and primary tourist attractions. St. Alexander Nevsky Cathedral in Sofia occupies an area of 3,170 square metres (34,100 sq ft) and can hold 5,000 worshipers. It is among the ten largest Eastern Orthodox church buildings. It is the largest cathedral in the Balkans. It is believed that up until the year 2000 it was the largest finished Orthodox cathedral.

Westminster Cathedral, officially the Metropolitan Cathedral of the Most Precious Blood, is the largest Catholic church in England and Wales. The shrine is dedicated to the Blood of Jesus Christ and is the seat of the Archbishop of Westminster.

The original site on which the cathedral stands in the City of Westminster was purchased by the Diocese of Westminster in 1885, and construction was completed in 1903. Designed by John Francis Bentley in a 9th-century Christian neo-Byzantine style, and accordingly made almost entirely of brick, without steel reinforcements, Sir John Betjeman called it "a masterpiece in striped brick and stone" that shows "the good craftsman has no need of steel or concrete."

The Cathedral of St. Vincent de Paul (Arabic: كاتدرائية القديس فنسون دو بول بتونس, romanized: Kātidrāʾiyyat al-Qiddīs Finsūn dū Būl bi-Tūnis; French: Cathédrale Saint-Vincent-de-Paul de Tunis) is a Roman Catholic church located in Tunis, Tunisia. The cathedral is dedicated to Saint Vincent de Paul, patron saint of charity. It is the episcopal see of the Archdiocese of Tunis and is situated at Place de l'Indépendance in Ville Nouvelle, a crossroads between Avenue Habib Bourguiba and Avenue de France, opposite the French embassy.

The church, designed by L. Bonnet-Labranche, was built in a mixture of styles, including Moorish revival, Gothic revival, and Neo-Byzantine architectural traditions. The cornerstone was laid in 1890, and construction began in 1893. The church was opened on Christmas in 1897, albeit without its belltowers owing to a shortage of funds. The reinforced concrete towers were completed in 1910 using the Hennebique technique.

The St. Alexander Nevsky Military Cathedral of Tiflis (Georgian: ტფილისის სამხედრო ტაძარი, tp'ilisis samkhedro tadzari; Russian: Тифлисский Александро-Невский военный собор, Tiflisskiy Aleksandro-Nevskiy voyenny sobor) was an Orthodox Christian cathedral in downtown Tiflis (now Tbilisi), Georgia, constructed during the Imperial Russian rule in 1871-1872 and 1889–1897 and demolished by the Soviet authorities in 1930. The novel design of the cathedral became a standard for the emerging Neo-Byzantine style well before the cathedral was completed.
