Different dynasties favored different regions for their summer retreats. The Capet and Valois dynasties favored the region north of Paris, especially Compiègne. The Bourbon dynasty preferred the forests to the est and the south, and Fontainbleau, in particular, would become the residence of choice for almost every French king. Several former royal castles adorn the region, such as Montargis and the archeological museum in Guedelon.
Ile-de-France and the Orleans regions of the old French Kingdom each claimed half of Gâtinais. However, both realms were always under the de jure control of the French crown, and the division was purely administrative. Gâtinais today is largely lost between the modern Ile-de-France region and the Loiret.
Historically there is little to write about in terms of regional identity. The forests and palace of Fontainbleau dominate the northern half. In the south, the Loire River is the primary driver of economic and cultural activity. In this sense, the modern administrative boundaries of the Loiret Department make sense.
