Baydar Gate, Mountain pass in Crimean Mountains near Sevastopol.

Baydar Gate is a 503-metre mountain pass in the Crimean Mountains between Mount Chelebi-Yaurn-Beli and Khuba-Kaya, linking the Baidar Valley with the Black Sea coast. In 1848 a Neoclassical propylaeum of local limestone blocks was built across the old Yalta–Sevastopol highway: a deep rectangular passageway flanked by two round fluted columns, with a broad stone band and a flat roof edged by a metal railing above.

The pass became significant in 1848 when a new road connecting Yalta and Sevastopol was completed, changing regional trade and communication. The stone gates were built as landmarks for this important route.

The pass frames views of Foros Church, which sits on a high cliff and reflects the region's religious traditions. This location links mountain scenery with expressions of local faith.

The site is accessible by a well-maintained road and lies along routes to popular hiking areas in the region. Several marked trails and overlooks near the gates allow visitors to explore on foot at their own pace.

The gate is too narrow for two cars to pass, so a bypass road runs alongside it. A staircase inside the propylaea leads to two viewing platforms above the passage, and the right-hand stone pier contains a room of about 30 square metres.
