Prague is not exactly Stonehenge but there is a curious alignment at the sunset on the summer solstice. If you stand at the Old Town Tower of Charles Bridge and look toward Prague Castle, the sun crosses the main tower of St Vitus’ Cathedral, lighting up the chamber with the crown jewels, goes past the small altar bell tower and sets on the roof before peeking out of the church’s apse and then setting again on the roof of the adjacent All Saints’ Church.
