Palais Porcia, Vienna

Palais Porcia is a former urban residence in the western quarter of the Innere Stadt of Vienna, Austria.

[2] In the 17th and later centuries it was extensively remodelled in Baroque and Rococo styles but the inner court still contains an early Renaissance arcade.

[3] In 1528 the cluster of buildings south of Freyung was purchased by the royal treasurer (German: königliche Pfennigmeister) Johann Löbl.

The new owner commissioned the rebuilding of old medieval structures, using arcades to blend them into a single stately residence with then-fashionable Renaissance facade.

Inside, the building acquired an ornate spiral staircase carved of "Royal limestone" (German: Kaiserstein) from Kaisersteinbruch.

[5] The library stocks a reference collection of Austrian laws and regulations and houses the information technology center of the Chancellery.
