Ordu–Giresun Airport — Ordu, Turkey

Ordu–Giresun Airport, coded OGU, is a notable engineering achievement located on the Black Sea coast of Turkey, built partially on reclaimed land extending into the sea to serve the twin provinces of Ordu and Giresun. Opened in 2015, this relatively modern airport was constructed to improve connectivity for a mountainous coastal region historically dependent on lengthy road travel or the more distant Trabzon airport. OGU offers domestic flights primarily to Istanbul and other major Turkish cities, supporting the local hazelnut farming economy and tourism to the scenic Black Sea highlands. The airport's unique construction, using land reclamation techniques, has made it something of an engineering landmark in Turkish aviation infrastructure. OGU has significantly reduced travel times for residents of this previously underserved region.
