Fort Vechten was constructed between 1867 and 1870 as part of the so-called Nieuwe Hollandse Waterlinie (The 'New Dutch Water Line') to defend the cities of the western Netherlands from overland attack.
The history of Vechten dates however back to the Roman times. The Romans, who apparently chose the spot because it controlled a side-arm of the Lower Rhine, built their castellum by the year 4 AD, and possibly named it after that river, Fectio. This fort was quite important from time to time as a supply-base for the invasion of Germany. It attracted the local population as well, which came to settle in the vicus at either end of the fort. The castellum was most likely abandoned by the late 3rd century, when the Roman Empire faced crisis after crisis. However, the main reason that the army never returned may well have been because the access to the fort silted up, which caused it to become land-locked, with all the ensuing logistical problems. The neighboring castellum at Trajectum/Utrecht may have supplanted it as local fort. Today there is a reconstructed Roman watch tower.

Le Lude is the most northerly château of the Loire Valley and one of the last important historic castles in France, still inhabited by the same family for the last 260 years. The château is testimony to four centuries of French architecture, as a stronghold transformed into an elegant house during the Renaissance and the 18th century. The monument is located in the valley of Le Loir. Its gardens have evolved throughout the centuries.
