Genoese forts along the Black Sea
In the 1300 and 1400s, well before Columbus sailed across the Atlantic, earlier Genoese voyagers were plying Turkey's coastlines, establishing a network of trading ports and routes that connected Crimea with the Mediterranean.
Though the Black Sea towns of Sinop, Amasra, Akçakoca, and Şile all contain Genoese traces, the coastline's most famous example of the onetime maritime republic's legacy is the crumbling Yoros Castle, set on a high hill overlooking the meeting of the Istanbul Strait and the Black Sea.
Wooden mosques of the Black Sea
Constructed entirely of chestnut wood and intricately decorated with carvings of trees, tulips, stars, and flowers, the mid-19th-century mosque in Şimşirli village in Trabzon is a fine example of the region's timber-built houses of Muslim worship.
Despite the threats posed by a damp climate and dramatic summer-winter temperature swings, dozens of wooden mosques from the same era persist along the Black Sea coast, though the original architecture of many has been altered by stone or metal minarets, roofs, and other later additions.
With its worn wood and sheet-metal reinforcement, the 160-year-old Maral Mosque in Artvin's Borçka town, for example, looks inauspicious from the outside, but its interior is an explosion of color, full of beautifully carved and painted details depicting scenes from the Quran.
Georgian monasteries and churches of Artvin
This remote northeastern corner of Turkey was once part of the medieval Georgian kingdom of Tao-Klarjeti, which left its mark on the spectacular landscape in the form of 10th- and 11th-century religious buildings scattered amidst the area's rugged peaks.
