One of two mosques from Selcuk times, the Alaeddin Paşa Camii. In a book I have the mosque is mentioned as a Selcuk mosque, so I am surprised to see the Wikipedia states it is from the 18th century. But an offcial page on the web has the same name, and tells us it was founded by a governor, Alaeddin Pasha. It's in the heart of the old town and has a fine atmosphere, and simple but nice decoration in stone. It probably was rebuilt at some point.
