Csíkkarcfalva is in Székelyföld (the land of the Hungarian Székelys), in Transylvania. Now it is in Romania and it is called Carta.
The village was born from the three villages of Karcfalva, Ábrahámfalva, and Tóthfalva. It is 23 km from the town of Csíkszereda.
It is famous for its gothic fortified church that was first mentioned in 1332. The church was rebuilt in 1444.
After 1396 the Turks began raiding Transylvania so the churches had to be fortified. There had been many Turkish raids in the area in the 17th century, too. It was the time when Ábrahámfalva and Tóthfalva got depopulated. Only Karcfalva survived that age, due to the walls around its church.
