The former manor house is one of the oldest (first half of the 18th century) buildings not only in Veisiejai, but also in the surrounding area. The Veisiejai Manor House was built in 1743 - 1745 by the Lithuanian Hetman Juozapas Mykolas Masalskis, who also planted the park and garden. The Veisiejai Regional Park Visitor Centre is located in the right flank of the Veisiejai Manor.
