The so-called 'Dediği Dede tekkesi' is located in the close vicinity of the villages of Mahmudhisar and Tekke near Ilgın. It is built on a hill-top overlooking the road passing through the settlements, a small pine wood covering the hills to the North and East. A badly built entrance gate of fairly recent date leads into a rectangular courtyard giving access to the building from the North, and surrounded by a wall about 2.5 m. in height. Within the building itself, three sections can be distinguished. From the courtyard the visitor passes into a rectangular chamber 17.40 m. long and 2.60 m. wide, the axis pointing in an east-west direction. As apparent from the construction joint in the south wall, this section is a later addition to the original building.

There is a double fountain of marble in the open - air display of the Archaeological Museum of İstanbul, situated in the first garden to the left of the Çinili Köşk. This monument (inventory number 3217) was first published by A. M. MANSEL in 1931. Its lower, main body is Byzantine, carved out of a monolithe marble with two niches. The crown cut at the top is a Turkish work. The back of this small monument, which was used as a fountain during the Turkish era, is covered with a decoration in relief, which clearly shows that originally it was a Byzantine work. Here are seen the curls of acanthus leaves, coming out of a kantharos and spreading symmetrically. In the middle there is a cross, whose lateral arms were wiped off during the Turkish era. We think that the lower part, that is, the section belonging to the Byzantine era, was originally related to a water system, and most probably it was also constructed as a fountain. Though the decoration at the back, by its motif and the technique of carving, indicates the VI and VII centuries, it should be taken into consideration that this type of embellishment was used until the XIIth century. During the Turkish era, this Byzantine monument was reshaped as a Turkish fountain during the XVI-XVII centuries, as is realized from the buds of the crown at the top.
