The Turkish Culture and Tourism Ministry started the restoration works on Sur-u Sultani, a four-kilometer (2.5-mile)-long section of Istanbul's ancient city walls located near the Topkapı Palace, which served as the residence of Ottoman sultans for four centuries.
The ministry allocated TL 25 million ($5.17 million) for the restoration project and it is estimated to be completed in 650 days, in November 2019.
