History runs deep throughout the entirety of Turkey, but you'll find each of the places described below in the Black Sea region, a strip of territory running across the north of the country from the outskirts of Istanbul all the way to the Georgian border.
Sümela Monastery
Perched in gravity-defying fashion on a cliff face near Trabzon, this is one of the oldest monasteries in the Christian world and a highlight of any trip to Turkey's Black Sea region.
Legend has it that the site's founder, an Athenian monk named Barnabas, had ventured into these wild, misty mountains in a successful quest to find a wooden icon of the Virgin Mary painted by St. Luke of Biblical fame.
The historic guild town of Mudurnu
The mountain town of Mudurnu, located midway between Istanbul and Ankara, was a key Silk Road stopover en route to Constantinople and a major Ottoman-era trading post and military base with close ties to the sultan's court.
Old wooden mansions from the 19th century, many with whitewashed walls, line the town center, where some traditional çamaşırhane over the river are still in use as communal laundry facilities.
Stone bridges of the Fırtına Valley
The lush Fırtına Valley east of Rize is home to nearly two dozen well-preserved stone bridges dating back to the Ottoman era, gracefully arching over the Fırtına River and its many tributaries.
Famed for its tea, honey, and hazelnut production, the valley was once home to numerous stonemasons, who are believed to have built most of the 20-odd bridges there in the 18th and 19th centuries.
Pontic rock tombs of Amasya
The rock tombs of the Pontic kings are the biggest draw to this picturesque town standing in the mountains above the Black Sea coast.
These monumental resting places, measuring up to 15 meters high and cut into the sheer cliffs towering over the Yeşilırmak River, pay tribute to the town's long-ago past as capital of the Pontic Empire, a Greek/Persian kingdom established in the 3rd century BC.
Safranbolu
An important caravan stop for nearly seven centuries, Safranbolu in north central Turkey grew prominent and wealthy, and its architecture and urban planning eventually influenced city development all over the Ottoman realm.
With its bucolic valley setting and dense concentration of restored timber-framed and red-roofed Ottoman houses, the UNESCO World Heritage Site is a popular weekend getaway for the in-crowds of Ankara and Istanbul, who come to stay in its boutique hotels, shop for handicrafts and sweets like yaprak helvası, and stroll (and photograph) its cobbled streets.
Old mansions of Çamlıhemşin
For an ambitious young man from Turkey's Black Sea region in the 19th century, Russia was the place to go to seek one's fortune.
The success of those who hailed from Çamlıhemşin, in the hills above Rize, can be seen today in the town's Konaklar neighborhood, where 200-year-old mansions line the steep slopes and give the neighborhood its name — Konaklar means "mansions" in Turkish.
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.
