The Temple of Apollo, also known as Portara, was built during the 6th century BCE and is one of the most significant historical landmarks on the island of Naxos. 

The style of architecture of the temple is Doric, and it has been beautifully preserved since the beginning of its construction. 

The temple was dedicated to God Apollo, who was the primary god of Naxos in ancient times. It was an essential religious and cultural center, with large celebrations and sacrifices held there during important ceremonies and festivities. 

Despite natural disasters and invasions over the years, the temple remains a vital part of Naxos’s history and attracts visitors from all around the world.
