The Apollakia dam was constructed in 1987 for irrigation purposes and the lake that was gradually formed began to turn into a significant wetland and an area for mild activities. On the banks there are picnic tables and small wooden houses for hosting scouts. In August rowing competitions are held. The most characteristic spot at the lake is the small church of Kimisi tis Thotokou (the Assumption of the Virgin Mary), which immerses in water when the lake is full. Near the Apolakkia dam the stone monastery of Ai Giorgis o Vardas (St. George Vardas) is located, one of the most important Byzantine monuments of Rhodes. It was built in 1289 during the era of Andronikos Palaiologos and it is renowned for its religious paintings.
