Gülhane Park, as the garden of the Topkapı Palace, has an important history and is among the first public parks in Istanbul. Information and guidance units were designed for this park, which has witnessed the history of the Ottoman Empire in the past and the Republic of Turkey today, dating back to the Byzantine period. The key words of this project were “nature” with its wide-range ecosystem, “history” with its witnessing the past, and “culture” with its museums in the region.
