Church of St. Margaret of Antioch is the only building still standing which certainly dates from the time of the Greater Moravian Empire. It is considered to be the oldest church in Slovakia. The church was built probably in the 9th or 10th century and was first mentioned in 1329. It was used until the 18th century when a new church was built in the village of Kopčany.
The church is an original pre-Romanesque building. It is a single-cell church with small rectangular chancel to the east chancel).The recent excavations have shown that the original church had a rectangular narthex at the west end of the church, and this contained a large stone lined tomb for the founding figure of the church. When the narthex was pulled down the Gothic arch which formed the entry at the west end, was inserted.
The first architectural survey of the church was conducted in 1964, the next in 1994. During investigations in 2004, three graves and jewellery from the times of Great Moravia were found outside the church. Currently archaeological research is focused on reconstruction of the historical landscape and its settlements. Also during this period the church has undergone further restoration work and the old render has been stripped from the walls. This now shows that the two arched windows on the north side of the nave are original while the windows on the south side were altered in the later Romanesque period. Since 1995, the church has been listed under Slovak cultural heritage. The outside of the church is openly accessible to the public. It stands in a field to the east of Kopčany and it is about 1.6 km from the major Greater Moravian site at Mikulčice, which is on the other side of the Morava river. It is approached by a road and is fairly close to the ruins of an 16th-17th century building which may have been a farm or manor house.References:
Angelokastro is a Byzantine castle on the island of Corfu. It is located at the top of the highest peak of the island"s shoreline in the northwest coast near Palaiokastritsa and built on particularly precipitous and rocky terrain. It stands 305 m on a steep cliff above the sea and surveys the City of Corfu and the mountains of mainland Greece to the southeast and a wide area of Corfu toward the northeast and northwest.
Angelokastro is one of the most important fortified complexes of Corfu. It was an acropolis which surveyed the region all the way to the southern Adriatic and presented a formidable strategic vantage point to the occupant of the castle.
Angelokastro formed a defensive triangle with the castles of Gardiki and Kassiopi, which covered Corfu"s defences to the south, northwest and northeast.
The castle never fell, despite frequent sieges and attempts at conquering it through the centuries, and played a decisive role in defending the island against pirate incursions and during three sieges of Corfu by the Ottomans, significantly contributing to their defeat.
During invasions it helped shelter the local peasant population. The villagers also fought against the invaders playing an active role in the defence of the castle.
The exact period of the building of the castle is not known, but it has often been attributed to the reigns of Michael I Komnenos and his son Michael II Komnenos. The first documentary evidence for the fortress dates to 1272, when Giordano di San Felice took possession of it for Charles of Anjou, who had seized Corfu from Manfred, King of Sicily in 1267.
From 1387 to the end of the 16th century, Angelokastro was the official capital of Corfu and the seat of the Provveditore Generale del Levante, governor of the Ionian islands and commander of the Venetian fleet, which was stationed in Corfu.
The governor of the castle (the castellan) was normally appointed by the City council of Corfu and was chosen amongst the noblemen of the island.
Angelokastro is considered one of the most imposing architectural remains in the Ionian Islands.
