Wejherowo is an important centre of pilgrimage in the region of Pomerania. The first service was conducted in 1652 in the monastic church of St. Ann, erected in the years 1648-1650 and located close to the town hall. In its superb late-Baroque interior, worshippers and tourists alike have a chance to admire the painting of the Virgin Mary of Wejherowo, which was crowned by Pope John Paul II.

Also, the town of Wejherowo is a charming place in terms of its attractiveness to anyone who loves nature. There are numerous monuments of nature hidden in the town and in the old century cemetery along 3 Maja Street. What is more, the cemetery is a site of historical relevance as it preserves some structures from the 19th century.

Prominently situated on the marketplace, the town hall in Wejherowo was built in 1650, although its present appearance is the result of an 18th century makeover. Wandering around the marketplace, one can spot a number of sacred buildings, and of these, the church of St. Leon deserves special attention. The one located the closest to the town hall is the Holy Trinity church, and while it dates back to 1643 it has been reconstructed time and time again, the last time in 1927.

Wejherowo is a home town of popular young Polish writer, Dorota Maslowska.
