The island of Sušac, the westernmost island of the Lastovo archipelago, located 13 nautical miles away, boasts a lighthouse. The Sušac lighthouse was built in 1878 on the highest peak of the southern part of the island. On the southern side, it is exceptionally steep, and the cliffs plunge into the deep and clear sea, which remains clear even at a depth of some thirty metres. The south-eastern side of the island gently descends towards the sea and abounds in beautiful coves and walking paths. The lighthouse has its own cistern, and electricity is provided by solar collectors with batteries. There are two ruinous churches in Sušac, the church of St. Nicholas from the 12th century, above Portić, and the church of St. Mary from the 15th century. On the northern part of the island, there are visible traces of houses, abandoned fields, olive groves and several smaller fields. The only inhabitants are lighthouse workers and a shepherd, who occasionally resides on the island.
It is located in Skrivena Luka, 7 km away from Lastovo and 17 km from the Ubli ferry port. The lighthouse was built in 1839 on the headland of the same name, and is one of the oldest on the Adriatic. The Struga lighthouse has a 20-meter-high cylinder tower, located at an altitude of 104 meters. Due to its distance from the coast, it seems lonely, and it appears as if it plunges into the blue of the sky and the open sea. It is located on the edge of a steep cliff, which gives an exceptional view of the open sea, while the light from the Struga lighthouse is visible up to 20 miles away and warns the boats that they are close to Lastovo. In its depths, the stunning cliff hides coral and gorgonia colonies.
At the easternmost island of the Lastovo archipelago, 9 nautical miles away from Lastovo to the east, there is the Glavat lighthouse. The Glavat lighthouse was opened in 1884 and it is among the largest buildings of this kind on the eastern part of the Adriatic. The lighthouse has its own cistern, and the light signalling device is powered by a battery that is supplied by an inverter and solar panels. The light is at an altitude of 45 meters and at night, it dominates the entire archipelago. The underwater world has a myriad of caves and stone boulders and is very attractive for diving tourism. Glavat is characterized by somewhat higher precipitation compared to other offshore islands of this part of the Adriatic. Thanks to this, the island can grow shrubs of bushy vegetation. Numerous legends are connected with Glavat, the most famous of which is the legend of the emergence of the island. According to this legend, Glavat was created thanks to a squabble between the gods of Olympus. The gods argued about which island is the most beautiful, Lastovo, Mljet or Korčula. Finally, Poseidon decided to send his emissary to decide on the spot. He emerged from the sea at the spot where Glavat is located today; he watched all three beautiful islands for three days because he could not decide which one is the most beautiful. To punish him, gods turned him to rock, or to the isle of Glavat.
