Palanka (fortification)

[11] Typical palanka had a rectangular plan and its entrance could be guarded by a watchtower called ağaçtan lonca köşkü.

[10] In order to increase resistance against cannon fire, wooden walls could be strengthened by applying mortar in a technique called horasani palanka.

Due to their makeshift aspect few palankas survive today but researches show that this kind of structures were used between 14th and late 19th century.

[12] Havale, which is the fortification that palanka was inspired by, acted as a base for troops and artillery during sieges of the early Ottoman era.

Havale type forts were also built during the Siege of Sivrihisar in Karaman, and in Giurgiu during the campaign to Hungary (1435–36) by Murad II.
