The secluded monument of the suburbs, the Turkish mausoleum, the türbe of Idris baba is located on the territory of the children's hospital.
Only little is known about the person lying in the mausoleum.
Contemporary historians say that he was a fortune-teller, a miracle man, whose miraculous deeds got publicity and therefore he was respected as a holy person.
The octagonal plan crypt with a dome was built in 1591.
There is a spherical section-shaped dome above the walls with a diameter of 6 metres and a height of 8.5 metres. Its facade contains windows on two levels, the lower windows being little unframed windows with ogee arches, the upper windows being round windows. The original entrance is left from the current entrance. Now it is walled up to form a niche. The Gothic stone frame of the current door may have been put in place during the reconstruction at the end of the 17th century. In the 18th century the türbe was used as a plague chapel.
The building was also used as a powder-magazine for long, that's why it was not pulled down.
In 1912 the türbe was partly restored but only got its current shape in 1961 when it became a historic monument and was renovated. The burial place of Idris Baba was also discovered in 1912, and his intact skeleton was also found. The burial place of Idris Baba was also discovered in 1912, and his intact skeleton was also found.
