Built in an opulent European style, Dolmabahce Palace (Dolmabahce Sarayi) was the home of the Ottoman sultans in the late 19th and early 20th centuries, before the fall of the empire. The giant crystal chandeliers, marble staircases, and lush carpets that adorn the interior reflect the shift toward Istanbul’s more European way of thinking.

Istanbul’s bustling waterside neighborhood of Ortaköy buzzes with the energy of bars, restaurants, cafés, and nightclubs. The main sight here is the Ortaköy Mosque (Ortaköy Cami), a 19th-century structure featuring a blend of baroque and neoclassical influences. Behind it, the Bosphorus Bridge looms, connecting the old Istanbul with the new.

The Bosphorus Bridge (Bogazici Koprusu) in Istanbul is one of three continent-spanning bridges over the Bosphorus Strait, connecting Europe and Asia. When it opened in 1973, the 5,118-foot (1,560-meter) bridge was the fourth-longest suspension bridge in the world. And though it has since slid down the rankings, it is still an impressive sight to behold.

Built over just four months, the 15th-century Rumeli Fortress played a key role in the fall of Byzantine Constantinople. Together with the Anatolian Fortress (Anadolu Hisarı) on the Bosphorus, Rumeli Fortress was used by the Ottomans to cut off aid and supplies to Constantinople. Today, it serves as both an open-air theater and site of historical interest.

Surprisingly for a city split between two continents, Istanbul existed without connecting bridges for most of its existence. After the construction of the Bosphorus Bridge in the 1970s, the second unifying bridge, Fatih Sultan Mehmet, came in 1988. It is part of Istanbul’s O-2 highway and connects the European and Asian sides of the city.

Located on the European shores of Istanbul, Emirgan Park (Emirgân Korusu) is one of the largest in Istanbul and serves as an oasis of nature in the urban sprawl. The park a popular weekend destination thanks to its jogging trails and picnic areas, and it is also the main venue for the annual Istanbul Tulip Festival, which blooms every April.

Commissioned in the mid-19th century by Sultan Abdulmecit, Küçüksu Palace (Küçüksu Kasri) Palace, aka Küçüksu Pavilion (Küçüksu Sarayı), was designed to be a summer palace for Ottoman sultans. The Istanbul palace’s design blends European and Ottoman styles, with an intricate carved exterior, sweeping staircases, and an interior with gilded accents and chandeliers.

Located in the shadow of Istanbul’s first bridge, Beylerbeyi Palace (Beylerbeyi Sarayi) was historically a summer residence for Ottoman sultans. The 24 rooms of the palace contain a mix of Ottoman and Western decoration, with 19th-century furniture from Europe and garden pavilions, and its ornate exterior is visible from the Bosphorus Strait.
