Ackerhof 2, Timber-framed heritage house in Brunswick, Germany

Ackerhof 2 is a two-story timber-framed house in Brunswick with visible wooden beams that form geometric patterns across the facade. The construction shows the regional building method with carefully fitted wooden elements and straightforward yet sturdy structural design.

The house is first recorded in Brunswick's house register in 1432 as "Borchard Smedes hus", and its north side bears the inscription "Anno domini m cccc xxxii". A 1774 fire damaged it heavily but left the roof structure, beam layers and parts of the rear and south walls as late-medieval original fabric. Dendrochronological testing in 2004 confirmed the core dates to 1432.

The name "Ackerhof" recalls the small square the house faces, which served as a distribution point for traffic and trade in the late Middle Ages. Since 1872 the ground floor has housed changing shops; a pet shop has operated there for several decades, and Delft tiles from an earlier butcher's shop survive on the southern interior wall.

The house stands on the small Ackerhof square in the Magniviertel, its eaves side facing the square and its rear facing Ölschlägern. The ground floor has housed a pet shop for several decades, so the building is not a residence; the 1432 inscription is on the north side, partly hidden by a downpipe and overpainted.

The date "Anno d[omi]ni m cccc xxxii" (1432) is carved on a plain beam on the north side, now damaged, wrongly repainted and partly hidden by a downpipe. Elmar Arnhold's 2004 report suggested the house could be Germany's oldest timber-framed building dated by an inscription.
