Alfeld, the chief place in the Leinebergland, lies on the right bank of the river Leine at the foot of the Sieben Berge (Seven Hills). Alfeld is noted for its flower nurseries (cyclamens) and has a varied range of industry.
On the Kirchhof in Alfeld are the Old Latin School (1610), with rich figural decoration and which now houses the Heimatmuseum, and the Municipal Museum (prehistoric material, regional history; dioramas).
Alfeld's Town Hall (1584-86) has a picturesque staircase tower. To the left of the entrance can be seen the "Blue Stone", which features in a local legend about the daughter of a burgomaster of Alfeld who was abducted by the robber knight Lippold von Rössing.
The Shoemakers' Guild-House in Alfeld an der Leine is a handsome half-timbered building of 1570. The town's oldest half-timbered building (1490) is at Seminarstrasse 3.
The twin towers of the parish church of Alfeld's St Nicholas, a 15th C. Gothic hall-church, dominate the old part of town. Notable features of the interior are the Triumphal Cross group, the font and the tabernacle.
The Lippoldshöhle, 1.5km/1mi southwest of Alfeld's Brunkensen suburb, is a cave in the depths of the forest. It consists of a number of chambers and passages which once (c. 1300) formed part of the castle of the robber knight Lippold von Rössing.
