Image result for GULHANE PARK
Gülhane Park was once the outer garden of Topkapı Palace, accessible only to the royal court. These days crowds of locals come here to picnic under the many trees, promenade past the formally planted flowerbeds, and enjoy wonderful views of the Bosphorus, Sea of Marmara and Princes' Islands from the Set Üstü Çay Bahçesi on the park's northeastern edge. The park is especially lovely during the istanbul tolip festivel, when tulips are arranged to resemble nazar boncuk 'evil eye' charms..
Green-fingered beautification has brought improvements to walkways and amenities, and the park has seen the opening of the istanbul museum of the history of science & technology in Islam 
Next to the southern entrance is the Alay Köşkü (Parade Kiosk), now open to the public as the Ahmet Hamdi Tanpinar Literature Museum Library.
Across the street and 100m downhill from the park's main gate is an outrageously curvaceous rococo gate leading into the precincts of what was once the grand vizierate, or Ottoman prime ministry, known in the West as the  Sublime Porte thanks to this flamboyant entrance. Today the buildings beyond the gate hold various offices of the İstanbul provincial government (the Vilayeti).
