The Holy Trinity Monastery (also known as Agia Triada) is situated at the top of a rocky precipice over 400 metres high and forms part of 24 monasteries which were originally built at Meteora. The church was constructed between the 14th and 15th centuries and is included in the UNESCO list of World Heritage Sites titled Meteora.
Holy Trinity was built in 1475–76, though some sources say the construction dates of the monastery and its adjoining chapel, dedicated to St. John the Baptist, are unknown.
The church plan is in the form of a cruciform type and has a dome which is supported on two columns. The monastery’s main cathedral was constructed in the 15th century and decorated with frescoes in 1741 by two monks. A pseudo-trefoil window is part of the apse. There are white columns and arches, as well as rose-coloured tiles. A small skeuophylakion adjoining the church was built in 1684. Its broad esonarthex barrel vault was built in 1689 and embellished in 1692. The small chapel of St. John the Baptist, carved into the rock, contains frescoes from the seventeenth century. It was richly decorated and had precious manuscripts; however, these treasures were looted during World War II, when it was occupied by the Germans. The building's sixteenth-century frescoes are reported to be post-Byzantine paintings. A fresco of St Sisois and the skeleton of Alexander the Great adorns the walls.
At one time, fifty monks lived at Holy Trinity, but by the early twentieth century, there were only five. Visitors are allowed. Patrick Leigh Fermor is reported to have visited the monasteries here several decades ago, as a guest of the Abbot of Varlaam. Even then, Holy Trinity was one of the poorest monasteries in Meteora.
References:The ancient Argos Theater was built in 320 BC. and is located in Argos, Greece against Larissa Hill. Nearby from this site is Agora, Roman Odeon, and the Baths of Argos. The theater is one of the largest architectural developments in Greece and was renovated in ca 120 AD.
The Hellenistic theater at Argos is cut into the hillside of the Larisa, with 90 steps up a steep incline, forming a narrow rectilinear cavea. Among the largest theaters in Greece, it held about 20,000 spectators and is divided by two landings into three horizontal sections. Staircases further divide the cavea into four cunei, corresponding to the tribes of Argos A high wall was erected to prevent unauthorized access into the theatron and may have helped the acoustics, but it is said the sound quality is still very good today.
Around 120 CE, both theaters were renovated in the Roman style.
