The Acropolis of Rhodes dates from the Classical Greek period (5th–3rd century BC) and is located approximately 3 kilometers from the centre of the city of Rhodes. The partially reconstructed part of the site consists of the Temple of Apollo (also, as alternatives Athena Polias and Zeus Polieus) below which is a stadium and a small theatre.
In 408 BC, towards the end of the Peloponnesian War, three of the island's ancient cities merged to build an entirely new one – the city of Rhodes – on a site in the Ialysia region of the island. Admired for its beauty and luxury, the city flourished. After weathering a siege by Demetrios Poliorketes (the besieger) in 305–303 BC, Rhodes rallied and built the Colossus of Rhodes, a massive statue of the sun god Helios, to whom Rhodes is linked in Greek mythology. The Colossus is known as one of the Seven Wonders of the Ancient World.
Following the great earthquake in 227 BC, which toppled the enormous harbor statue and devastated the city, Rhodes was rebuilt. It was later raided by Cassius in 42 BC and never recovered.
The Acropolis is situated on the highest part of the city. The monuments were built on stepped terraces, with substantial retaining walls.
Located at the northern extreme of the Acropolis in an east-west orientation, the Temple of Athena Polias and Zeus Polieus was dominated by Doric columned porticos on all sides and originally housed the written treaties the Rhodians held with other states. The temple was bounded by a stoa to the east.
Smaller than the Temple of Athena Polias and Zeus Polieus, Temple of Pythian Apollo boasts a similar east-west orientation but is located on the southern end, just west of a large rectangular terrace. Part of the northeast side of this porous peripteral temple has been restored.
Located on the southeast side of the hill, the 210-metre north-south Stadium was initially restored by the Italians. Its surviving features include the sphendone (rounded end with turning post), proedries (officials' seats), and some of the spectator seating. The starting apparatus used in the athletic events has also been preserved. Athletic events of the Haleion Games, honoring Helios, were held here.
References:Visby Cathedral (also known as St. Mary’s Church) is the only survived medieval church in Visby. It was originally built for German merchants and inaugurated in 1225. Around the year 1350 the church was enlarged and converted into a basilica. The two-storey magazine was also added then above the nave as a warehouse for merchants.
Following the Reformation, the church was transformed into a parish church for the town of Visby. All other churches were abandoned. Shortly after the Reformation, in 1572, Gotland was made into its own Diocese, and the church designated its cathedral.
There is not much left of the original interior. The font is made of local red marble in the 13th century. The pulpit was made in Lübeck in 1684. There are 400 graves under the church floor.
