The church has medieval origins, with the earliest building dating from the 1100s. It was enlarged around the end of the 1200s or start of the 1300s, when a barrel vault was added, and a brick vault followed in the 1500s. As the congregation grew, the church proved too small despite a new gallery built in 1620, leading to a rebuilding between 1673 and 1678 that gave the church its present chancel and sacristy. Further alterations and restorations followed, including a thorough restoration in 1905–1906. Today the church consists of a nave with a straight-ended chancel to the east and a lower, narrower sacristy to the north, all under tarred timber shingle roofs.
A freestanding open timber bell tower has stood on a rise north of the church since 1789. South of the church, a memorial grove (minneslund) was established in 2005.
Among the fittings, two fonts survive: a Romanesque sandstone font from the 1100s, and a later hexagonal oak font with ebony fillets from the late 1600s, a gift from Christina Sparre. The pulpit now in use was made by Per Wilhelm Palmroth and installed in 1811, replacing an earlier one donated in 1642. The altarpiece, by an unknown artist, was given to the church in 1789.
One of the more striking objects is a large funerary monument to Knut Kurck and his wife Barbro Dag och Natt, carved in Antwerp by the Flemish sculptor Nicolaes Millich. Originally intended for Stora Mellösa church, it proved so dominating there that parishioners had it removed after Kurck's death; his third wife Christina Sparre then had it re-erected, in simplified form, at Näshulta in 1704. It was moved again in 1951 to the south wall of the sacristy. Kurck's funeral hatchment also hangs in the church, along with a copy of a medallion by Johan Tobias Sergel depicting Jacob Jonas Björnståhl, a local-born scholar.
The church holds a range of older silver and textiles, though much was lost or melted down over the centuries to fund new pieces; a surviving 17th-century chasuble and a bridal crown are among the few older textile items still kept. The current organ was built in 1906 by E. A. Setterquist & Son of Örebro, incorporating the case from an earlier 1792 instrument, and was later enlarged in 1960.
