Kasteel Ter Aa

Kasteel Ter Aa is a medieval castle ruin in Nieuwer-Ter-Aa that stands at the junction of Ruwielstraat and M. van Zantenstraat, marking the historical center of the village. The site shows traces of its past even though modern homes were built over the former castle grounds.

This location was first documented in 1106 when it served as a residence for the Van der Aa family, who held the position of bailiffs for the Bishop of Utrecht. This status made the family an important power in regional administration and control.

The name 'Aa' comes from Old Dutch and means water, reflecting this castle's close ties to local water management and land development. This connection shaped how the surrounding area developed and how people lived here.

The grounds are privately owned and not freely accessible, as they are overlaid with modern homes. Visitors can recognize the location and street layout from public spaces to understand the historical position.

The Van der Aa family surpassed the influence of both Van Woerden and Van Amstel families by 1170, as shown in legal documents from that period. This early dominance reveals how quickly local families built their power in this region.
