On the headland above the harbour sits the ruins of the 14th Century Castle of the Knights of St John, one of many Crusader Fortresses built throughout the Dodecanese. This is now home to the island museum and houses some interesting artefacts and archealogy. The Greek flag proudly flies from the top most point of the fortress.
This impressive looking church in the square at the top of the hill was never finished, the coloumns inside the church are reputedly from the ancient ruins of Patara in Turkey. By the side of the church near to the Mediterraneo Taverna is the Ossuary or Honeftiro in Greek, it has a small plaque with a skull and cross bones above the door.
As well as the school in the square there are the churches of Agios Spiridion and Agios Panagyria {the Virgin Mary}.
Just beneath the Castle on the path around the cliff side is a lonely little Lycian Tomb from the 4thC BC.
The Turkish Lycian coastline has an abundance of these tombs carved into the rock and with such close proximity to this area, it is inevitable that there would be similarities in the archaeology.
Right at the harbour entrance is the little Ottoman Mosque which has been restored andnow houses an Ethnological Museum with a small but nice collection of photographs, doors, utensils, jewellery and local costumes.
Up the hill close to the airport is the Paleocastro, or Acropolis.
The ruins may not be of great interest to many but you can scramble around for a good hour. Probably the best time to go is just before sunset as the vantage point is superb for sunset photos over the surrounding small islands and sea.
Behind the harbour on the top road are the whitewashed stone steps that lead all the way up the mountain.
This is a wonderful walk with views over the harbour, surrounding islands and Turkey. At the top of the mountain is the large church of St George of the Mountain, and if you scout around the flat rocks in this area you will come across the ancient 'patitiria' circles carved into the rock for crushing olives and grapes.
The Blue Grotto {Parasta} which is found just after Navlakas Bay is well worth a visit. The early morning light shines into the cave turning the water into a shocking blue and lighting up the stalactites. The cave is quite large at 75 meters long, 40 wide and 35 high, making it a rival to the famous Blue Grotto in Capri.
Several taxi boats make the trip throughout the day, depending on the weather. Sometimes the sea can be too high or too rough to enter safely, so the alternative is to swim in-but beware it gets very cold!
