With its tufa hills creased into folds, surrounded by vineyards and orchards, and fairy chimneys of all sizes standing like stone minarets in an extraordinary natural landscape, the Güllü Dere Valley is a remarkable sight. The valley is dotted with hidden chapels decorated with beautiful frescoes, such as the 7C Church of Three Crosses, which houses a Christ Pantocrator flanked by angels, and the 8C-9C Church of St John, adorned with a portrayal of the Apocalypse.
