Of all the Troodos churches, I've only been to the only one easily accessible by public transport from Nikosia - the one in Galata. We took the effort to go there from Famagusta in Northern Cyprus and were very much disappointed. The paintings were nice but nothing out of the ordinary. I have seen much more beautiful ones even in Nicosia. Only the paintings in the apsis survived (and one other fragment) which was also a bad surprise as I imagined them to cover the entire church (again like in Nicosia). The church was badly lit (in order to preserve the frescoes) and the apsis which is the only interesting section of the church was not accessible to anyone but the local priest. So even in the dusky inner room of the church we still had to admire the paintings through a wall! A (partial) compensation for this unrewarding visit was the nearby charming village of Kakopetria with its cubbled streets. I sure hope the rest of the Troodos churches are better!
