Hildebrandt, Johann Lukas von
Hildebrandt took over responsibility (1703) for the design of the Church of St Peter, Vienna (begun 1702 by Gabriele Montani), planned as a longitudinal ellipse crowned by a cupola, flanked by two rectangular compartments and an apsidal choir. The tall entrance-front is flanked by twin towers set at angles, giving great drama to the composition. Franz Jänggl (1650–1734) was involved in the construction of the building. A variant of the plan of the Peterskirche was used for the Seminarkirche (Seminary Church), Linz (1717–25). From 1698 Hildebrandt worked (possibly with a contribution from K. I. Dientzenhofer) on the beautiful Piaristenkirche (Piarist Church) of Maria Treu, Vienna (built by Jänggl, 1716–31), which has a similar plan to that of the Gabel church. Completed (1751–3) by the Piarist Mathias Gerl (1712–65), the church is by far the lightest and most joyous in a city where the Baroque tends to be sombre.
Hildebrandt's greatest work is arguably the Belvedere, Vienna (1714–24), the dream-palace of Prince Eugen, with almost oriental roofs and frothy façades with shaped pediments and corner towers. There are, in fact, two buildings—the Upper and Lower (1714–16) Belvedere—linked by a series of terraced gardens, with statuary and planting. The Upper Palace contains the most celebrated of Hildebrandt's staircases where massive, struggling atlantes carry heavy vaulting. He also designed the staircase with urns and putti at Schloss Mirabell, Salzburg (1721–7). Other fine staircases can be found at the Palais Daun-Kinsky, Vienna (1713–16), and Schloss Weissenstein, Pommersfelden (1711–15)—where he also designed the central pavilion. From 1720 to 1723 and again from 1729 to 1744 he collaborated with Neumann on the Residenz of the Prince-Bishop at Würzburg: his hand is evident in the shaped pediments of the central pavilion as well as in the Kaisersaal ( Emperor's Hall) and Chapel. He was involved in the rebuilding of the Stift (Monastery) of Göttweig from 1719: his plans were ambitious but never fully realized, although the building containing the Kaiserstiege (Emperor's Stair) of 1738 is as fine as anything he conceived.
