Rydboholm Castle is a historic structure situated near the village of Rydbo in Österåker Municipality, within Stockholm County and the province of Uppland, Sweden. While the site's origins trace back to the medieval period, the current castle complex, characterized by three interconnected wings surrounding an open courtyard, primarily dates from the 16th century. The main building was constructed in 1548, and the estate underwent significant reconstruction during the 18th century. The grounds feature a large park designed in the English style, which was established in the early 19th century by Magnus Fredrik Brahe.

The castle holds considerable historical significance due to its association with prominent Swedish dynasties. From the 15th century onward, it served as the property of the Sture family before passing to the House of Vasa. Notably, some historical sources suggest that King Gustav I of Sweden was born at Rydboholm Castle, and following 1520, the estate belonged to his sister, Margareta Eriksdotter Vasa. Ownership later transferred to the influential Brahe family. Through inheritance and marriage, the property eventually passed to the von Essen family and subsequently to Count Gustaf Douglas and his wife Elisabeth von Essen.

Today, Rydboholm Castle remains a notable landmark in Stockholm County, reflecting centuries of architectural evolution and noble heritage. Although specific details regarding its current public accessibility or modern functional use are not explicitly detailed in available records, the structure stands as a testament to Sweden's royal and aristocratic history. The combination of its 16th-century architecture, 18th-century modifications, and 19th-century landscaped gardens makes it a unique example of Swedish castle development through the ages.
