Mountainous Tinos is the spiritual center of modern Greece, and it is sometimes called the Lourdes of the Aegean. The focus of the religious activitities is an icon housed in the church that dominates the town: the Panagia Evangelistria. The icon is a piece of late Byzantine art, which they say originates from a church destroyed by pirats in the 10th century. It is believed to have healing powers. It came to light in 1822 after a nun had a vision and it was dug up miraculously uninjured. The church was then build on the discovery site. The church has a dresscode, but I didn't see it mentioned anywhere, so I walked in in short pants and a t-shirt in order to burn a candle. There is a main road (used also for the processions) and a souvenir road (nice, you can buy 2 metres long candles for christmas!) leading to the church. It's really very beautiful on the inside, and also the courtyard surrounding it and the views are worth a visit.
