Pandėlys Manor was known as early as the days of the Grand Duchy of Lithuania. In the 17th century the manor belonged to the Rajecki family, and later its owners changed. The manor buildings have not survived; only the 5.4 ha manor park remains, which, although it has lost its original appearance, still delights the eye with avenues of maples and lindens, impressive wych and European white elms, thick oaks, maples and ashes. Laid out by M. Koscielkowski in the first half of the 19th century, the park was in the style of the Italian Romantic era, arranged in squares linked by gravel paths. It was adorned with carriage drives. Carp were bred in the pond, and on holidays the manor's residents sailed on it in an ornate gondola.
