You needn't be of strong faith to appreciate the peaceful atmosphere of Kaunas Cathedral. Check when the next service starts or when it's open for general viewing.
Kaunas Cathedral is an ideal place to begin discovering Old Town Kaunas. This principal church is recommended by fellow travelers, but it's not the only spot to see here. Set aside time for other attractions like Kaunas Castle, Ninth Fort, and Vytautas the Great War Museum to fully experience what the area has to offer.
