Goldburg, Castle ruin in Murstetten, Perschling, Austria

Goldburg is a castle ruin located in the municipality of Perschling in Lower Austria, with stone walls standing on elevated ground that overlook the surrounding area. The structure retains multiple sections of walls that showcase their original construction despite their deteriorated condition.

A castle stood at Murstetten from 1140 until Turkish troops destroyed it during the first siege of Vienna; the Althan family acquired the site by marriage in 1526. In 1580 they began building the Goldburg slightly above the old site in Italian Renaissance style, and in 1644 it was converted into a Baroque palace. Turkish troops damaged it again in 1683, and from 1706 Johann Bernhard Fischer von Erlach remodelled it for Count Gundacker von Althan. In 1809 Napoleonic soldiers were quartered in the empty palace; after a soldier was found stabbed in the courtyard, the commander had it set on fire, and it was never rebuilt.

The site is still owned by the Althan family, who live in Zwentendorf an der Donau. The name Goldburg refers to the Renaissance palace begun in 1580, not to the earlier castle. Only parts of the garden wall remain in the centre of Murstetten, and the area is overgrown and protected as a monument.

The site lies in the centre of Murstetten, in the municipality of Perschling, and only remnants of the garden wall survive, overgrown with scrub. Access is on foot from the village; the terrain is level, not a climb. The area is a protected monument and remains private property of the Althan family, so visitors should keep to the visible remains.

The site is still owned by the Althan family, who live in Zwentendorf an der Donau. The Czech sources also record that a surviving building of the former estate is the mausoleum above the parish church.
