Kartuzy has long been a cultural center of the Kashubians. Since 1947 a Kashubian Museum has featured numerous exhibits connected to Kashubia and its inhabitants. The town has also set up a bust to honor Dr. Aleksander Majkowski, author of The Life and Adventures of Remus, who practiced medicine in Kartuzy for a time and is buried here. In 2010, the Kashubian Unity Day was held here. On March 28, 2010, after the Holy Mass in the fourteenth-century collegiate church, Kashubes in colorful regional costumes with black-and-yellow flags passed through the streets to the Team of Schools No. 2 for Wybicki's Estate where the main celebrations were held.
