One of the most interesting cultural and historical monuments of Chania is the Turkish Janissaries Mosque (Yiali Tzami, known as well as Giali Tzami). The majestic old building dominates the Venetian harbor of Chania and it is hard to miss.

The story begins Janissaries Mosque in 1645 after the Ottoman Empire occupied a large part of the island of Crete. At that time, a significant part of the Greek church was converted into a mosque (as a sign of the power of the Great Ottoman Empire). An important task of the Turkish conquerors was to draw as many Christians in their faith. They were forced to convert to Islam and Christian boys captured and then raised them in strict obedience and religious devotion.

Studies have found that the mosque was built on the ruins of the old Venetian bastion. Janissaries Mosque is a huge square with a large dome resting on arches, and seven small domes. The interior of the mosque is made in the Turkish style, but some elements are preserved from the times of the Venetian era. Unfortunately, the minaret of the mosque to the present day has not been preserved as it was demolished in the early 20th century (during the Greek War of Independence against the Turks). At that time, nearly half of Chania professed Islam, and Janissary Mosque was one of the most visited places in the city.

In 1923 the authorities were exchanged as part of a public plan for repatriation. As a result, Muslims in the city almost gone, and the mosque has lost its main purpose. For a long time the building was used as a warehouse. Today, in the premises of the mosque hosts art exhibitions. There is also a tour desk.
