This agrarian community is mainly visited by those who want a look at Keldby Kirke, Præstegårdstræde 1, Keldby (tel. 55-81-33-05). Built of brick between 1200 and 1250, this is one of the island's special churches, celebrated for its frescoes that span 200 years, the oldest dating from 1275, with both Old and New Testament scenes included. No church in Denmark quite equals Keldby in medieval frescoes -- note especially the dramatic representation of Cain and Abel and the horror show depicting Armageddon. Shepherds pictured with their flocks create a more bucolic scene. In addition to the frescoes, the church contains a number of other treasures, notably a carved pulpit dated 1586, and, in the vaulting, paintings by the Master of Elmelunde, including a tender depiction of Joseph preparing gruel for his newly born infant son. A tombstone at the north side of the church dates from the mid-14th century. Admission is free, and the church can be visited April to September daily from 7am to 4:45pm, off-season daily 8am to 3:45pm.

If you have time after viewing the church, visit the manor Hans Hansens Gård, Skullebjergvej 15 (tel. 55-81-40-67), which lies about 1.5km (about a mile) south of Keldby Church. (Follow the signs to Keldbylille to reach it.) Dating from 1800, this is a thatch-covered building whose wings enclose an inner courtyard. Originally conceived as a farmhouse, it's the home of Møns Museumsgården, a monument that depicts what family life was like for homesteaders during the 1800s. The farm was kept in the same family for generations. When its last owner, a bachelor, Hans Hansens (for whom the property is named), died, he willed it to the people of Møns, who converted it into a museum. Furniture and utensils used by the Hansens family are on display. Open April to September, Tuesday to Sunday 10am to 4pm, charging DKK35 ($6/£3.50) for admission.

The highway (Rte. 287) continues directly east to Elmelunde.
