The Silivrikapı (Silivri Gate) lies to the north of the Belgrade Gate and is distinguished by its two polygonal towers, both of which are still standing today. The Greeks referred to it as “Pege”, named after the nearby Church of Zoodochos Pege, meaning “the Life-Giving Spring.” The name Pege remains visible on the southern wing of the staircase. 

During the Late Byzantine period, the name evolved into Selivria (modern-day Silivri), after a Byzantine city to which the road from this gate once led. On the upper section of the gate, one can still see the names "Basil" and "Constantine" inscribed. The outer wall with the arch was added during the Ottoman era, though the original Byzantine masonry remains clearly recognizable beneath it. 

Following the Ottoman conquest of the city, Sultan Mehmed II established a new neighborhood within the city walls. The gate was later restored after the Great Earthquake of the 16th century under the reign of Bayezid II. 

To the right of the entrance stands the tomb of Elekli Dede (meaning “Grandpa Sieve”). The famous 17th-century traveler Evliya Çelebi recounts that Elekli Dede was said to have eaten only food sifted through a sieve made from animal hide. Today, the gate has been renovated following the 1999 earthquake and serves as a pedestrian passage connecting the city’s inner and outer parts.
