The Patriarchal Cathedral of the Holy Ascension is a former Eastern Orthodox cathedral in the city of Veliko Tarnovo, in north central Bulgaria. Located on top of the fortified Tsarevets hill in the former capital of the Second Bulgarian Empire, the cathedral was the seat of the Bulgarian patriarch from its construction in the 11th–12th century to its destruction in 1393.
The current building of the Patriarchal Cathedral is considered by scholars to have been built in two stages. The first stage of construction was carried out in the late 11th century or the 12th century. The cathedral was initially built as a monastery church in the middle of a monastery compound, though in the early 12th century it was already the seat of the Bulgarian patriarch. The compound suffered large-scale damage caused by a fire, which necessitated the church's reconstruction in middle of the 14th century. Besides repair and reinforcement efforts, work on the church in the 14th century also included the construction of the exonarthex and the bell tower.
The Patriarchal Cathedral was destroyed after the Ottomans captured the Bulgarian capital after their Siege of Tarnovo on 17 July 1393. Reconstructed in the 1970s and 1980s, it follows a cross-domed plan with a bell tower and a triple apse. Richly decorated on both the exterior and interior, its internal walls now feature modern frescoes, the presence of which has meant that it has not been reconsecrated. Though not active as a Christian place of worship, it has been open for visitors since 1985.
References:Rosenborg Palace was built in the period 1606-34 as Christian IV’s summerhouse just outside the ramparts of Copenhagen. Christian IV was very fond of the palace and often stayed at the castle when he resided in Copenhagen, and it was here that he died in 1648. After his death, the palace passed to his son King Frederik III, who together with his queen, Sophie Amalie, carried out several types of modernisation.
The last king who used the place as a residence was Frederik IV, and around 1720, Rosenborg was abandoned in favor of Frederiksborg Palace.Through the 1700s, considerable art treasures were collected at Rosenborg Castle, among other things items from the estates of deceased royalty and from Christiansborg after the fire there in 1794.
Soon the idea of a museum arose, and that was realised in 1833, which is The Royal Danish Collection’s official year of establishment.
