Creevykeel Court Tomb is one of the finest examples of a court tomb remaining in Ireland. The monument is located in the N15 Donegal to Sligo road, 50 meters north of Creevykeel cross-roads close to Cliffoney village in County Sligo.
The building of the tomb dates back to the Neolithic Period, 4000-2500 BC, when waves of colonising farmers migrated to Ireland from the continent. The Creevykeel Court Tomb is one of five megalithic monuments in the area. Creevykeel has not been dated using modern scientific methods, and is estimated to date from about 3,500 BC with a long span of use and re-use.
The monument consists of a long, trapezoid-shaped cairn of stones which measures 55.5 meters along its east - west axis, 25 meters at the wider eastern facade, and 10 meters wide at the western end or tail of the cairn. The stones used to construct the monument are a hard local sandstone with a bluish tint.
The cairn encloses an oval-shaped full court 15 by 9 meters with an entrance passage through the east side. The entrance to the main chamber is located at the centre of an imposing megalithic facade on the west side of the court. The chamber is made up of two large compartments divided by a pair of jambs which presumably supported an inner lintel like those at Shawley and Croaghbeg in County Donegal.
Evidence of large corbel slabs used for roofing the structure survives in the inner chamber. In the west end of cairn three subsidiary chambers were built into the body of the monument, which have been described as being small passage-graves. However they seem to date from a later neolithic addition to the original monument.
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.
