Chiesa di San Giovanni Battista, Religious building in Lumezzane, Italy.

The chiesa di San Giovanni Battista in Lumezzane has a northwest-facing gabled facade split by a string course into two registers, each with six pilasters; the Tuscan lower order frames a portal with a broken curved pediment, the Ionic upper order has a large window and a triangular pediment. Inside, a single nave with side chapels under round arches and pilasters supporting a barrel vault leads to a raised presbytery and polygonal apse.

The church was built in the 12th century on the site of Roman ruins and underwent major renovations in 1570 under architect Lodovico Beretta. This rebuilding established much of the structure visitors see today.

The church's name comes from the ancient pieve of San Giovanni Battista, likely at Piubego; the Pieve temple first held both titles before keeping only this one. The 16th-century frescoes of the earlier building were recovered between 1978 and later restorations and are now kept in a room next to the sacristy, not in the side chapels.

The church is located in the Pieve district and continues to serve as an active place of worship. Visitors should dress appropriately and be respectful during any services that may be taking place.

The bell tower, added in 1691, has a square base with a single round-arched opening on each side and is topped by a crenellated crown. The 1695–1700 reconstruction by Carlo Bianchi followed two years after the community decided to enlarge the church again.
