The Vecihi gate at Sapanca is counted among the surviving works of Ottoman architecture. Nothing about it is put forward as established: it is said to have been built by Mimar Sinan, and it is related that the historic Silk Road passed by the spot where it stands.

It is 17 kilometres from the city centre and is reached by city transport.
