There is an area where three tombs stand together in a small park. I here show pictures of what in Turkish are the Üç Kümbetler.
A text on the web, translated and condensed, states: "Emir Saltuk Tomb is made of cut stone. It has an octagonal body, a high drum and is covered with a flat cone that is a mixture of dome and conical. There are animal reliefs such as bulls, snakes, bats and eagles on the triangular pediments, round arches and tambour niches of the tomb made of two-coloured cut stone. These reliefs resemble the zodiac figures in Central Asian Turkish calendars. The human head engraving between the bull horns in one of the niches attracts attention. There is a pair of windows on each of the four sides of the eight facades of the Emir Saltuk Tomb. Geometric decoration and flower and animal figures can be seen on the eaves of the northern entrance of the tomb. The lower part of the second tomb, located in the southeast of Emir Saltuk Tomb, has a square plan and twelve facades. This tomb is made of gray stone. It has one small window at the top and three large, decorated windows at the bottom. The window on the south side of this tomb also looks like a mihrab. The third tomb, 4 meters away from the second tomb, is made of local keyek stone. It has twelve sides and four windows. There is a beautifully decorated mihrab inside the tomb, which has an entrance door in the north direction. There are decorations similar to the Emir Saltuk Tomb on the rim of the conical cone covering the tomb.
