Hawthornden Castle comprises a 15th-century ruin, with a 17th-century L-plan house attached. The house has been restored and now serves as a writer's retreat. Man-made caves in the rock beneath the castle have been in use for much longer than the castle itself.
The castle comprises a roughly triangular courtyard, approximately 24m long and 12m at its widest point, projecting north-west along a rocky promontory on the south bank of the River Esk. The 15th-century tower is situated at the south-east corner. Around 8m square, the tower is ruined, although the recent renovation included the installation of a library in the tower basement. There is also a rib-vaulted pit prison beneath the tower. Windows on the south curtain wall show that a range of buildings once stood here, although these are now all gone. A well in the west end of the courtyard supplied the castle's water.
The 16th century range is to the north, and is linked to the tower by a 16th-century wall, in which is the entrance. The range is of three storeys and an attic, and was originally harled. The renaissance-style doorway is of later date, as is the iron knocker with the initials of Sir William Drummond (the son of the poet) and his wife, Dame Barbara Scott. There are three gunports around the doorway, with a fourth in the tower. The last addition to the castle was a single-storey range to the west, built in the late 18th or early 19th century.

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.
