The Tirana Mosaic is believed to have been part of a 3rd century Roman house, referred to by local archeologists as the 'Villa rustica'. Later, in the 5th and 6th centuries, a Paleo-Christian Basilica was built around this site.
The ruins of this Paleo-Christian Basilica were discovered in 1972. In 2002, some other objects were found around the ruins of the house, and today they form the Archaeological Complex of the Mosaic of Tirana. It is the only archaeological monument within the city. Some of the ancient mosaics discovered at the site that feature diverse geometrical patterns and depict poultry and fish.
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.
