The Il-Arslan Mausoleum is Konye-Urgench’s oldest standing monument. The conical dome, with a curious zigzag brick pattern, is the first of its kind and was exported to Samarkand by Timur. Il-Arslan, who died in 1172, was Tekesh’s father. The building is small but well worth a close look. The conical dome with 12 faces is unique, and the collapsing floral terracotta moulding on the facade is also unusual.
