St. Hallvard's Cathedral (Hallvardskatedralen), the former Oslo Cathedral, was the earliest cathedral in Oslo. The cathedral was built at the height of the Old Town market square Oslo during the early 12th century, and was used as a church until about 1655. Besides being the bishop's seat and religious center of eastern Norway for about 500 years, the cathedral was the coronation church, royal wedding church, chapel royal, and one of Scandinavia's most visited place of pilgrimage. St. Hallvard cemetery is located mainly south of the cathedral. It was the honorary cemetery in Oslo and eastern Norway from around 1130 to 1639. Here the bishops, chiefs and other prominent men and women were buried. The most prominent was interred in the church along with the kings.
Today the cathedral is in ruins. The main body in the ruins park (Memorial Park), the southern part under a concrete cap - and the concrete lid of the street of Bispegata. Towards the end of the 19th century were Bispegata extended in an easterly direction, over the cathedral site. It has been put in place to remove Bispegata's eastern part, as a result of the completion of the Ekeberg Tunnel and the modified veian resort in the lower Lodalen. In that case, the ruins of St. Hallvard Cemetery exposed, and the Medieval city triangular marketplace, Oslo squares, re-established west of St. Hallvard Cemetery. Neighboring the Cathedral was the smaller Church of the Cross.References:
The Church of the Savior on Spilled Blood is one of the main sights of St. Petersburg. The church was built on the site where Tsar Alexander II was assassinated and was dedicated in his memory. Construction began in 1883 under Alexander III, as a memorial to his father, Alexander II. Work progressed slowly and was finally completed during the reign of Nicholas II in 1907. Funding was provided by the Imperial family with the support of many private donors.
Architecturally, the Cathedral differs from St. Petersburg's other structures. The city's architecture is predominantly Baroque and Neoclassical, but the Savior on Blood harks back to medieval Russian architecture in the spirit of romantic nationalism. It intentionally resembles the 17th-century Yaroslavl churches and the celebrated St. Basil's Cathedral in Moscow.
The Church contains over 7500 square metres of mosaics — according to its restorers, more than any other church in the world. The interior was designed by some of the most celebrated Russian artists of the day — including Viktor Vasnetsov, Mikhail Nesterov and Mikhail Vrubel — but the church's chief architect, Alfred Alexandrovich Parland, was relatively little-known (born in St. Petersburg in 1842 in a Baltic-German Lutheran family). Perhaps not surprisingly, the Church's construction ran well over budget, having been estimated at 3.6 million roubles but ending up costing over 4.6 million. The walls and ceilings inside the Church are completely covered in intricately detailed mosaics — the main pictures being biblical scenes or figures — but with very fine patterned borders setting off each picture.
In the aftermath of the Russian Revolution, the church was ransacked and looted, badly damaging its interior. The Soviet government closed the church in the early 1930s. During the Second World War when many people were starving due to the Siege of Leningrad by Nazi German military forces, the church was used as a temporary morgue for those who died in combat and from starvation and illness. The church suffered significant damage. After the war, it was used as a warehouse for vegetables, leading to the sardonic name of Saviour on Potatoes.
In July 1970, management of the Church passed to Saint Isaac's Cathedral (then used as a highly profitable museum) and proceeds from the Cathedral were funneled back into restoring the Church. It was reopened in August 1997, after 27 years of restoration, but has not been reconsecrated and does not function as a full-time place of worship; it is a Museum of Mosaics. Even before the Revolution it never functioned as a public place of worship; having been dedicated exclusively to the memory of the assassinated tsar, the only services were panikhidas (memorial services). The Church is now one of the main tourist attractions in St. Petersburg.
