The Patriarchal Monastery of the Holy Trinity is a Bulgarian Orthodox monastery in the vicinity of Veliko Tarnovo. Founded in the Middle Ages, it was reconstructed in 1847 and again in the mid-20th century. The Patriarchal Monastery is situated on the banks of the Yantra River within its Dervent Gorge. On the opposite bank of the river is located another medieval cloister, the Transfiguration Monastery.
There are at least a few theories with regard to the monastery's exact foundation, all pointing to the Middle Ages. According to an inscription discovered during the construction of the present monastery church, it was founded in 1070. Two other theories link the monastery's establishment with the religious and cultural upsurge of the Second Bulgarian Empire in the mid-14th century.
The Fall of Tarnovo to the Ottomans in 1393 meant an end to the monastery's heyday, and by 1416 the Bulgarian Patriarchate had been subordinated to the Patriarchate of Constantinople. Despite being arsoned, it nevertheless continued to exist, and in the 18th and early 19th century it was regularly the subject of donations by the rulers of Wallachia and Moldavia, the Romanian principalities across the Danube.
In the early 19th century, the Patriarchal Monastery suffered two disasters. In 1803, a brigand raid plundered its buildings, and in 1812 an outbreak of plague caused the abandonment of the already hardly active cloister. The monastery was, however, reestablished in the 1840s. The monastery church was built in 1846–1867 The monastery church follows a cross-in-square plan with three domes, which were added later. Blind arches with red brickwork inside decorate the exterior, and a four-columned exonarthex marks the west entrance.
The altar of the current church was brought from the Ancient Roman ruins of Nicopolis ad Istrum. In antiquity, it was used as a pagan sacrificial altar. The interior decoration and the iconostasis of the church were the work of Samokov painter Zahari Zograf.
The church, along with the entire monastery, suffered extensive damage during an earthquake in 1913. The church was reconstructed in 1927, while the adjacent buildings were rebuilt after World War II, in 1946–1948, when the monastery was converted to a nunnery. However, Zahari Zograf's frescoes have not been restored, and the interior of the monastery church remains for the most part unpainted. At present, the monastery complex includes the main church, residential buildings, chapels dedicated to Jesus Christ and Evtimiy of Tarnovo and a well, as well as the grave of Metropolitan Joseph of Veliko Tarnovo (1870–1918).
References:The Church of St Donatus name refers to Donatus of Zadar, who began construction on this church in the 9th century and ended it on the northeastern part of the Roman forum. It is the largest Pre-Romanesque building in Croatia.
The beginning of the building of the church was placed to the second half of the 8th century, and it is supposed to have been completed in the 9th century. The Zadar bishop and diplomat Donat (8th and 9th centuries) is credited with the building of the church. He led the representations of the Dalmatian cities to Constantinople and Charles the Great, which is why this church bears slight resemblance to Charlemagne's court chapels, especially the one in Aachen, and also to the Basilica of San Vitale in Ravenna. It belongs to the Pre-Romanesque architectural period.
The circular church, formerly domed, is 27 m high and is characterised by simplicity and technical primitivism.
