Stora Sundby castle was mentioned first time in Middle Ages. In 1364 it was besieged and captured by Albrecht during his battle with Magnus Eriksson. From the end of 1300s to the early 1400s it belonged to Lars Ulfsson Blå. After him Stora Sundby was owned by Julita monastery and families of Natt och Dag, Sparre and Chevron.
The present main house was built by Lars Siggesson Sparre, who asked Carl de Geer to design a new castle on the old Norman style. The casle was finished in 1848. The drawings were made up by the English architect J.F. Robinson. In refurbishment underwent castle a fundamental change in the exterior but the interior remained mainly unchanged. The architecture symbolizes a year calendar: 52 rooms (number of weeks per year), 12 small towers (12 months per year), four large towers (four seasons), 365 windows (days per year).
