Imperial Exiles & Victorian Timber Palaces
Büyükada (historically known in Greek as Prinkipos, meaning 'Prince') was chosen as an imperial retreat by Byzantine Emperor Justin II in 569 AD, who constructed an imperial palace and monastic foundations on its eastern slopes. Throughout the medieval era, its secluded hilltop monasteries served as secure exile redoubts for royal rivals. Empress Irene was deposed in 802 AD and confined to a cloistered convent here. Following the 1453 Ottoman conquest, the island transitioned into quiet fishing communities under the spiritual aegis of the Ecumenical Patriarchate.
The inauguration of regular steamship service in 1846 transformed the island into the premier summer colony of late-Ottoman high society. Greek bankers, Armenian industrial architects, and European diplomats commissioned opulent summer villas along Çankaya Caddesi and Nizam Caddesi. These homes represent masterworks of late-nineteenth-century timber framing, featuring ornamental wooden friezes, cast-iron balustrades, Victorian turret roofs, and classical pediments.

Experience Büyükada's grandest mansions without exhausting uphill walking. Includes central Istanbul hotel pickup, round-trip ferry crossing, guaranteed seating on the official electric island shuttle route, and a traditional Turkish lunch at a local garden restaurant.
Dilburnu Nature Park & Swimming Coves
Covering 6.88 hectares on Büyükada's western cape, Dilburnu Nature Park (Dilburnu Tabiat Parkı) extends into the Marmara Sea beneath shaded stone pine groves (Pinus pinea and Pinus brutia). The reserve charges an entrance fee of 60.00 TL per adult and provides wooden picnic tables, sea-facing walking trails, and direct platform access to shallow pebble swimming in Değirmen Koyu.
Cycling Precautions: While cycling around Büyükada's southern perimeter (the Great Tour route / Büyük Tur) is widely popular, the steep descent from Lunapark Square down toward Nizam features sharp hairpin curves on cracked asphalt frequently coated with slippery pine needles. Maintain low speeds and test your rental bicycle handbrakes before starting your ride.
Gastronomy, Historical Bakeries & Seafood Precautions
Culinary exploration on Büyükada offers authentic Aegean flavors if you know where to steer away from tourist traps. Avoid generic soft-serve stands surrounding the clock tower square and seek out established confectioneries like Tarihi Prinkipo Dondurmacısı (operating near the pier since 1952) and Büyükada Roma Dondurmacısı. These shops churn traditional mastic-infused ice cream (damla sakızlı dondurma) prepared with goat and buffalo milk. Outstanding seasonal flavors include roasted almond, wild blackberry, and sour black mulberry (karadut).
For breakfast or lunch, explore local bakeries along Çarşı Caddesi for fresh, flaky börek filled with curd cheese or minced beef, paired with hot Turkish black tea. When dining on fresh Marmara fish along the waterfront harbor, exercise consumer caution: fresh catches displayed on ice beds are frequently priced per 100 grams rather than per portion. Always verify the exact whole-fish price and kilogram weight before cooking, and confirm whether unrequested meze appetizers or bread baskets brought to your table carry additional cover charges.
