Sveta Nedelya, is an Eastern Orthodox cathedral in Sofia, the capital of Bulgaria. The history of the cathedral's earliest years is to a large extent unknown. It was probably built in the 10th century and had stone foundations and an otherwise wooden construction, remaining wooden until the middle of the 19th century, unlike most other churches in the city.
Around 1460, the remains of Serbian king Stefan Uroš II Milutin were carried to Bulgaria and were stored in various churches and monasteries until being transferred to St Nedelya after it became a bishop's residence in the 18th century. With some interruptions, the remains have been preserved in the church ever since.
The former building was demolished to make place for a larger and more imposing cathedral in 1856. The construction of the 35.5 m-long and 19 m-wide church began in the summer of the same year. The still incomplete building suffered from an earthquake in 1858, which prolonged the construction works that ultimately finished in 1863. A new belfry was erected to accommodate the 8 bells given to the church as a present by Russian Knyaz (Prince) Alexander Mikhailovich Dondukov-Korsakov in 1879.
The church was renovated in 1898, with new domes being added. Exarch Joseph I of Bulgaria was buried immediately outside the walls of St Nedelya in 1915. The church was razed in the bomb attack in 1925 that claimed over 150 victims. After the incident, the church was restored to its modern appearance between the summer of 1927 and the spring of 1933. It was almost erected anew as a temple 30 m in length and 15.50 m in width and featuring a central dome that made it 31 m high. The gilt iconostasis that survived the bomb attack was returned to the church.
The mural decoration was done by a team led by Nikolay Rostovtsev between 1971 and 1973. The floor was renovated and the north colonnade was glazed between 1992 and 1994. The façade was cleaned thoroughly in 2000 and a device to automatically ring the eleven bells (the eight ones from Knyaz Dondukov-Korsakov, two made in Serbia and one cast in Bulgaria)
References:Visby Cathedral (also known as St. Mary’s Church) is the only survived medieval church in Visby. It was originally built for German merchants and inaugurated in 1225. Around the year 1350 the church was enlarged and converted into a basilica. The two-storey magazine was also added then above the nave as a warehouse for merchants.
Following the Reformation, the church was transformed into a parish church for the town of Visby. All other churches were abandoned. Shortly after the Reformation, in 1572, Gotland was made into its own Diocese, and the church designated its cathedral.
There is not much left of the original interior. The font is made of local red marble in the 13th century. The pulpit was made in Lübeck in 1684. There are 400 graves under the church floor.
