This little church situated at the very end of ul. Grodzka, just in front of Wawel Hill, might not be as exciting as some of Kraków other places of worship, but it's worth a mention for at least one reason: English-language mass each Sunday at 10:30. And St. Giles' is quite historical as well - its first iteration was built here in the 14th century, though local legend pushes that date even further to the 11th century, when Duke Władysław I Herman was to rejoice the birth of his only child, a boy later known as Duke Bolesław III Wrymouth. Originally Benedictine, the church currently belongs to the Dominican Order, along with the more impressive Holy Trinity Basilica.
