Schloss Oranienhof, Baroque palace in Bad Kreuznach, Germany

Schloss Oranienhof was a four-winged Baroque palace built around 1669 in the Neustadt of Kreuznach, converted from the former Pfalz-Simmern princely court by engineer Johann Rudolf Stürler for Maria of Orange-Nassau. It was a modest building compared with the other Orange palaces, with four or five rooms fitted as a dwelling and a flower garden on a thick tower looking out over the fields. French troops plundered and burned it in 1689; nothing of the palace itself survives.

Maria of Orange-Nassau commissioned the palace in 1669 on the site of a former Augustinian convent. Major reconstruction took place after French troops destroyed the structure during the Palatinate War.

The name Oranienhof comes from Maria of Orange-Nassau, who had the former Palatine-Simmern princely court rebuilt as her summer residence around 1669. The name later passed to the estate on the opposite bank of the Nahe, where the Oranienpark is today. Nearby field names such as Oranienberg, Oranienwiese and Oranienstraße still recall her.

Nothing of the palace on the Hochstraße survives; the name passed to the former estate on the opposite bank of the Nahe, now the Oranienpark about 1,250 metres away. Look for the street and field names Oranienberg, Oranienwiese and Oranienstraße that still recall Maria of Orange-Nassau. Stones from the estate were reused in the Wilhelmskirche around 1698–1700.

The palace stood on the site of the abandoned Augustinian convent of St. Peter, founded around 1140 and dissolved in 1566/68. Maria of Orange-Nassau turned part of the empty convent into a model dairy with some twenty milking cows and a "menage for her pleasure"; a small pleasure palace there was never finished because of the wars.
