Stoutenburg is a village in the Dutch province of Utrecht. Until June 1, 1969, Stoutenburg was an independent municipality. In 1812 she joined Hoevelaken until she became independent again in 1818. Since 1969 it has fallen under the municipality of Leusden. The village has about 350 inhabitants.
In Stoutenburg, you can admire castle Stoutenburg. The current '' castle of Stoutenburg '' is a mansion built in 1888 as a successor to a series of former fortresses. The first castle of Stoutenburg was founded in 1259 by Willem van Amersfoort. It served to protect the border between the Count of Gelre and the bishop of Utrecht. However, there has never been a garrison. The name means: "Proud castle". As mentioned, the estate Stoutenburg at Leusden has a long history. The history of the estate begins at an episcopal castle of the 13th century, possibly resulting from an older age tower (= donjon) from the 11th century. In 1259 the castle was under construction. On 12 June 1259, the day Amersfoort received city rights from bishop Hendrik I van Vianden, Walter (or Wouter), Mr. van Amersfoort and Eemland's scholar, settled in Stoutenburg. In exchange for the disposal of this castle, the then bishop of Utrecht granted city rights to Amersfoort. The bishop used the castle to camp war crimes. The religious order of the Lesser Brother Franciscans bought the neglected house in 1948 and made a monastery. The late Franciscan Francisans left the building at the end of 1990 to make way for the community of the Franciscan Environmental Project, the 'Milieuklooster'. That community is still there and also has its own offer about spirituality and natural affiliation. Activities are organized throughout the year.
