The Promontor palace (‹See Tfd›German: Schloss Promontor or Hungarian: Promontor Kastély) is a former baroque-style palace in Budafok, a southwestern neighbourhood of Budapest, Hungary. The quadrangular castle was built between the vineyards on the hills on the right side of the Danube river. It was commissioned by Prince Eugene of Savoy (1663–1736). The design can probably be attributed to Johann Lukas von Hildebrandt (1668–1745).
Today, only the stable buildings remain of the Promontor palace. Nothing is left from the main building, except an 18th-century plan by the architect Franz Xaver Hacker in the Hofkammerarchiv in Vienna, Austria.[1]
