LAMBACH. - A Benedictine abbey in Upper Austria, in the diocese of Linz; it has 5 incorporated parishes, an agricultural and horticultural school, and a retreat house.
St Adalbero, Count of Wels and L., later Bishop of Würzburg, founded around 1040 a house for canons regular in his ancestral castle at L.; but around 1056 he introduced Benedictine monks from Gorze. Suppressed by Joseph II (1784), it was almost immediately restored; during the Nazi period it was again suppressed (1941-45). The present church, built in 1652-1656, replaced two earlier ones, one Romanesque and the other Gothic; it contains famous altarpieces by Sandart. In the monastery rebuilt in Baroque style between the 17th and 18th centuries, the summer refectory is noteworthy. The most famous abbot was Maximilian Pagl (1705-25).
Not far from L. stands the famous shrine church of Stadl-Paura, dedicated to the Most Holy Trinity, which the aforementioned Abbot Pagl had built (1714-24) by J. M. Prunner of Linz. A church of great artistic merit and highly original architecture: circular in plan, with an inscribed triangle (v. AUSTRIA), three bell towers, three portals, three altars, and three organs; the interior is extremely rich.
