The Old Castle
The oldest and most important monument of the island, Paleokastro, is located on the western side of Kastellorizo, about one kilometer from the capital. It is the ancient acropolis of the island built around the 3rd century BC and used up to the period of Italian occupation. Within the settlement were houses, cisterns and churches of the Middle Byzantine period, of which two were destroyed during the First World War. Nowadays surviving parts are buildings and water tanks, as well as parts of the wall and within those the churches of the Castle Virgin Mary and St. Stephen, which are associated with a pebbled floor from 1858. In the area of Paleokastro in Limenari, remain the ruins of the Cyclopean walls, while in the Doric acropolis, from the 3rd BC, sights can be seen where the term "Megisti" is written. Visiting the site of Paleokastro can be done in the morning and to get there you must follow a dirt road that ends in a trail road, however the panoramic views offered will reward you.
The Castle of the Knights of Saint John
The Castle of the Knights of St. John also known as the Great Castle, towers above the village, at the top of Castello Rosso, the red rock that named the island. In the 14th century, when the Knights occupied the island, they built the castle, using materials from the ancient citadel. Today only the ruins of the interior and of the walls remain from the castle, however a visit there offers a lovely view of the harbor of the island and the coast of Asia Minor.
The Blue Grotto
One of the most impressive monuments in the Mediterranean, located in Kastelorizo and particularly in the south of the island is the famous Blue Grotto a.k.a. "Cave of Parasta" or "Fokiali" (from the seals that live in). With a height of 35 meters and a width of 40 meters, the Blue Grotto awe visitors with rich stalactite decoration, which is highlighted from the reflection of the sunrays, creating a unique spectacle. Apart from the thousands of pigeons that are hosted, the Blue Grotto also has a very interesting seabed, where rare and unique varieties of fish live. Travelling to the Blue Grotto can only be done by boat, as its entry allows only small boats to pass through.
The Lycian Tomb
The emblematic monument of the island, the Lycian Tomb, is located east of the harbor. The Lycian tomb essentially symbolizes the relationship of the island with the coasts of Asia Minor, namely the inhabitants of the Lycia region, where people worshiped "Lykio Apollo" as a wolf. Its dated back to the 4th century BC and it is chamber - styled, with its front to niche carved into the rock. The door is decorated with a triple band and in the inside there are funeral beds on 3 sides, arranged on 2 levels. Visiting the Lycian tomb can be done in the morning hours and admission is free.

The Island of Ro
From Kastellorizo you can sail to the small island of Ro that is located just three nautical miles north of the island. This small island was known throughout the world, due to the Lady of Ro, which for years was the only resident and every morning raised the Greek flag. "The lady of Ro", whose real name was Despoina Achladioti contributed greatly to the National Resistance during the World War 2 occupation and for 40 years raised the Greek flag every sunrise and brought it down with the sunset, until 1982, where she died at the age of 92 years. In her honor a monument was erected. On the island there are two beautiful beaches, the "Stroggyli" and "Saint Stephen".
Saint George of the Mountain
A four hundred stairs separate the island port from Saint George of the Mountain, an abandoned castle-like monastery. The monastery of Saint George of the Mountain is surrounded by enormous rocks that form its wall, wherein the most dilapidated monks cells and auxiliary chorous are contained. It is a single-nave styled church built on the site of an early Christian basilica, part of which survives to date along with the mosaic floor and capitals incorporated in the masonry of the church. In the western part lie the catacombs of Saint Charalambos, which are connected with the temple's steps. According to the inscription on the lintel of the ledger, the temple was restored by Saint Anthimos from Cephalonia in 1759, and a carved iconostasis with 18th century icons is of special interest.
