This card shows Lala Mustafa Pasha Mosque – originally known as Saint Nicholas's Cathedral – in Famagusta, Northern Cyprus. It was consecrated as a Catholic cathedral in 1328 and was converted into a mosque after the Ottoman Empire captured Famagusta in 1571. It remains a mosque to this day. The building strongly resembles Reims Cathedral and its Rayonnant Gothic style is quite rare outside of France.
Turkish Republic of Northern Cyprus has eluded me for quite a long time, so a massive "thank you" is due to Rosaleen and John, my better half's mother's neighbours, who took time out of their holiday and looked past our very tenuous connection to send this card to me. And another big thanks to Annette for talking me up to the neighbours and arranging for this card to be sent. I'm forever grateful to you all.
Information about Turkish Republic of Northern Cyprus stamps is rather hard to come by. Beyond saying that they were released in 2015 and, quite clearly, feature a dog, not much more I can add. Cute dog though.
