St. Petersburg, Russia, is the home of the Church of the Resurrection of Jesus Christ, also known to locals as the Church of the Savior on the Spilled Blood. The cathedral marks the spot where Alexander II was fatally wounded in 1881. After his father's death, Alexander III declared his intention to erect a church on the site in his father's memory. It was built in traditional Russian style in response to what he saw as the contaminating Western influence of St. Petersburg.

La Sagrada Família is a giant basilica in Barcelona that has been under construction since the late 1800s and is not expected to be complete for many years to come. The large, unfinished Roman Catholic church was designed by Spanish architect Antoni Gaudi. This stunning sacred site caught the eye of Pope Benedict XVI in 2010 and he consecrated it, proclaiming it a minor basilica. This amazing cathedral was designed by Gaudi to mimic nature.

The Kölner Dom of Cologne is a Gothic masterpiece built to honor the faithful of Germany. Construction began almost 700 years ago and took more than 600 years to complete. This UNESCO World Heritage Site is laid out in a Latin cross, a trademark of Gothic cathedrals. The interior is just as impressive. Its 104-seat medieval choir section is one of the largest in existence. As a testament of faith, the Kölner Dom still stands after being struck by 14 bombs during WWII.

Notre Dame de Paris is making news today not for its grandeur, but for the tragic fire that wreaked havoc on the iconic cathedral in April of this year. This tragedy may be the biggest and saddest art story in recent times. Pope Alexander III laid the cathedral’s foundation stone in 1163 and the church has been a focus of attention through the ages. Napoleon saved it from destruction and crowned himself emperor in the cathedral in 1804.

The Hagia Sophia has had a diverse religious history that dates back to its inception. From 537 until 1453, it served as an Eastern Orthodox cathedral and the seat of the Patriarch of Constantinople. During the 13th century, it was briefly turned into a Roman Catholic cathedral as part of the Fourth Crusades. Then, from 1453 until 1931, it was an Ottoman mosque until it was secularized and opened as a museum in 1935. It is said that its massive dome, typical of Byzantine design, changed the history of architecture. The Hagia Sophia held the record as the world’s largest cathedral for 1000 years.

If you follow the British Royals and their weddings, then Westminster Abbey looks very familiar. There have been at least 16 royal weddings at the abbey since 1100, beginning with Henry I. The building itself was a Benedictine monastic church until the monastery was disbanded in 1539. Technically, the Abbey is not a cathedral, but has the status of a Church of England “Royal Peculiar.” This means that the church is responsible directly to the crown.
