Mimar Sinan incorporated a triangular base design to increase stability against both wind and earthquake forces.
The aqueduct was part of a larger project spanning over 50 kilometers of channels and tunnels.
It is often cited as the pinnacle of Sinan's structural engineering, even surpassing his mosque designs in technical complexity.
The structure features a unique 'wide-arched' design on the lower level, which minimizes wind pressure compared to traditional solid walls.
Despite its age, the structure has survived multiple major earthquakes in the Istanbul region without collapsing.
The water conduit at the top is still identifiable, demonstrating the original gravity-fed flow path.
During the construction, Sinan used iron cramps to secure the stone blocks together.
Mağlova Su Kemeri is a 16th-century Ottoman water bridge designed by the royal architect Mimar Sinan. Completed in 1564, it serves as a central component of the Kırkçeşme water supply system that historically provided Istanbul with fresh water. The structure spans the Alibey Creek valley and features two tiers of arches, demonstrating advanced hydraulic engineering and seismic resilience. It is constructed from cut stone and stands approximately 36 meters high with a length of 258 meters. The bridge was reconstructed after a major earthquake destroyed it in the late 16th century. It remains one of the most prominent examples of Ottoman civil architecture and water management infrastructure. Visitors can walk along the lower level of the aqueduct to observe the massive masonry blocks and original water conduit channels.

Wear hiking-appropriate footwear as the terrain leading to the aqueduct can be uneven and steep.
Bring your own drinking water as there are no vendor facilities directly at the site.
The area is largely unmonitored; visit during daylight hours for safety.
