The castle tower is a fragment of the oldest building in Tukums. It is believed that the construction of the castle in Tukums was commenced in 1277 by the Livonian Order. The castle was surrounded by a 7.5 m tall and 1.6 m wide stone wall. The castle defence was ensured by an artificial, deep moat and its position on the high bank or the River Slocene. Only a small stone wall fragment has been preserved from the castle, but the castle tower built in the 18th century in turns hosted premises for a prison and the caronal stocks (granary). Nowdays, it hosts the history museum of Tukums town, telling about the town's history from the ancient times up until the modern day.
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.
