Sigtuna
Sigtuna is a town north of Stockholm, Sweden. It's known for the stone ruins of St. Olaf's, St. Lawrence's and St. Peter's medieval churches. St. Mary's Church, built by Dominican friars, still stands in the center. Stora Gatan, said to be Sweden's oldest main street, dates back to the time of 10th-century King Erik the Victorious. Today it's full of shops and restaurants in traditional wooden houses.
