magic brick

A Lithuanian postcrosser sent this lovely card of the cathedral in Vilnius. I love the banks of clouds in the sky and the people in the square around the church. But there is more. Greta, the sender, wrote that there is a 'miracle brick' located between the cathedral and its tower. You must find the brick, stand on it, look at all three saints on the cathedral, turn around three times, and make a wish! She did it and her wish came true, which is why she really believes 'that this brick is magical.'
