LAMBACH. - Benedictine abbey in Upper Austria, in the diocese of Linz; it has 5 incorporated parishes, an agricultural and horticultural school, and a retreat house.
S. Adalberone, count of Wels and L., later bishop of Würzburg, founded around 1040 in his native castle of L. a house for regular canons; but around 1056 he introduced Benedictine monks there from Gorze. Suppressed by Joseph II (1784), it was almost immediately re-established; during Nazism it was again suppressed (1941-45). The present church, built in the years 1652-1656, replaces two earlier ones, one Romanesque and the other Gothic; it has celebrated altar paintings by Sandrart. In the monastery rebuilt in Baroque forms between the 17th and 18th centuries, the summer refectory deserves notice. The most celebrated abbot was Massimiliano Pagl (1705-25).
Also worthy of mention, near L., is the celebrated sanctuary church of Stadl-Paura, in honour of the Most Holy Trinity, which the said abbot Pagl had built (1714-24) by J. M. Prunner of Linz. A church of great artistic merit and most original architecture: circular in plan, with an inscribed triangle (v. AUSTRIA), three bell towers, three portals, three altars, three organs; the interior is exceedingly rich.
