Castle Gate is one of the symbols of Kuşadası and is part of the city walls built by Konevi Mehmet Pasha in the 17th century. It is the entrance section known as the south gate, whose upper floor was once used as a police station. This square-planned tower-shaped gate is probably one of the three main entrance gates in the Ottoman period. According to a local belief, those who pass under this castle gate can never leave Kuşadası again and become Kuşadası residents.

The museum, which has a magnificent intact structure and is now used as "Kuşadası Municipality Necati Korkmaz Micro Miniature Art Center and Museum", is used to exhibit over 40 micro miniature works of art, some of which are considered the smallest works in the world.

This exhibition center, located in a unique historical place of the 17th century and the third of its kind in the world, is open to visitors seven days a week for those who want to experience the meeting of modern art with an environment that is more than two hundred years old.
