By the new year, the Turkish State Mint releases a new commemorative coin depicting the Chora Church / Museum located in Istanbul.
The coin is silver proof as most of the latest TR comm. coins.
About the Chora Chuch (copy from Wikipedia):
The buiilding is considered to be one of the most beautiful examples of a Byzantine church, and is situated in the western, Edirnekapı district of Istanbul.
In the 16th century, the church was converted into a mosque by the Ottoman rulers, and it became a secularised museum in 1948.
The interior of the building is covered with fine mosaics and frescoes.
