St. Mary's Church (Marienkirche) is a large Lutheran church built some time before 1298. It is architecturally Gothic, an example of the brick gothic style prevalent in northern Germany. Between 1625 and 1647, it was the tallest building in the world at 151 metres tall.
The bell tower collapsed in 1382, and was rebuilt by 1478. In 1495, the steeple tower blew down during a severe storm, and was then rebuilt taller. This was subsequently struck by lightning in 1647, and burned down, and was rebuilt as a baroque dome, which, completed in 1708, can be seen today. The tower is currently 104 metres tall.
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.
