The present Invermark Castle is on the site of a 14th-century castle. The castle belonged to the Lindsays of Crawford. It was designed to control Highland marauders. It was here that David Lindsay, 9th Earl of Crawford died in 1558. The present castle was built in the 16th century, and heightened in the early 17th century. The castle was abandoned in 1803.
The 16th-century castle was a three-storey structure, having a corbelled parapet and parapet walk. The additions were another storey and a garret, and a two-storey angle-tower. The castle walls have rounded corners. Two massive chimney-stacks have window-openings giving the garret light.
The entrance, at first floor level, was reached by a movable timber bridge or stair. The entrance, a rounded arch, which still has an iron yett, led to the hall, to which a small room is attached. A wheel stair was the only access to the vaulted basement. The turnpike stair by which access could be gained to the upper floors, which were also subdivided, no longer exists.
The entrance to the castle is barred and well above ground level, making the interior virtually inaccessible to visitors.
There are foundations of outbuildings to the east and south of the tower; material known to have been robbed from the site to build the parish church probably came from here.
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.
