The village was first mentioned in 1383 as Niewekuyc, which means "new settlement of
Cuijk". The family of Cuijk used to own land in the area. Castle Onsenoort was built in 1382 by the
heer of the
heerlijkheid Nieuwkuijk. In the 19th century, it became part of the
Cistercian monastery Mariënkroon. The tower probably dates from the 14th century. The monastery buildings were built in 1910. The main building and gate were added between 1934 and 1935. In 2016, the abbey closed down. It is now used as a conference centre. The floods of Nieuwkuijk in 1880 shocked the whole of the Netherlands. From mid-December onwards, the Meuse water level was so high that many villagers became anxious. On 30 December, the dike broke and in the days that followed, the water flowed so rapidly that people could not be rescued from their roofs with boats. The entire land of Heusden and Altena was flooded. It was not until 18 January that the construction of a new dike could be started, and completed one month later. The new dike, 600 m long, was built by Nicolaas van Haaren together with Wouter Pietersz. de Vries. Nieuwkuijk was home to 978 people in 1840. In 1997, it became part of the municipality of
Heusden. ==Gallery==
