The Sopot Pier, built as a pleasure pier and as a mooring point for cruise boats, first opened in 1827. The next reconstruction extended the length of 150 metres, then to 315 m. The pier was brought to the contemporary length in 1928, along with the walking passage of the spa. The first non-wooden elements appeared after 1990, when the head was modernised using steel elements.
At 511.5m, the pier is the longest wooden pier in Europe. It stretches into the sea from the middle of Sopot beach which is a popular venue for recreation and health walks (the concentration of iodine at the tip of the pier is twice as high as on land) or public entertainment events, and it also serves as a mooring point for cruise boats and water taxis. It is also an excellent point for observing the World Sailing Championship, the Baltic Windsurfing Cup and the Sopot Triathlon taking place on the bay. Sopot pier consists of 2 parts: the famous wooden walking jetty and the Spa Square on land, where concerts and festivities are organised.
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.
