St. Peter und Paul, Church building in Ergoldsbach, Germany.

St. Peter and Paul is a hall church with a transept, rounded-arch windows and a small ridge turret over the crossing. On the west side stands a baroque tower with a square four-storey base, set-back upper storey, spire and lantern. The nave of four bays carries a barrel vault with lunettes, separated by Tuscan pilasters; the choir and both transept arms close in three sides of an octagon, and a two-storey sacristy adjoins the choir to the south.

A church existed in Ergoldsbach by 822, when Bishop Baturich of Regensburg held a meeting there. The 1606 town fire spared the parish church, but a dilapidated predecessor was replaced in 1693; its tower collapsed in 1698 and a new one followed in 1709. After the 1726 market fire destroyed church and tower, rebuilding finished in 1729, funded by parishes of the Regensburg diocese and neighbouring communities. The tower was added only in 1750, paid for by postmaster Franz Niederneder.

Until 1860 church records name only the Apostle Peter as patron; Peter and Paul appear together for the first time in a 1916 diocesan register, and their feast day is 29 June. In the crossing, four baroque figures stand diagonally: Peter and Paul flank the chancel, while the Archangel Michael and Brother Konrad face the nave.

The church stands on the west side of the market square, its tower rising above the surrounding buildings. The main entrance is through the round-arched portal at the base of the tower. Inside, the 1999 Schädler organ with 25 registers is played during services; the instrument's classical case comes from the previous organ.

The four bells sound the notes e1, gis1, h1 and d2. The church also keeps an organ built in 1999 by Orgelbau Schädler of Donaustauf, with 25 stops on two manuals and pedal, played from a separate console; its upper case was taken over from the previous instrument.
