Von Ahnska magasinet, a port warehouse located on Storgatan in Ume, Sweden, was demolished in 1888.
The building survived the great fire of 1888. During the same year, the merchant Johan Viktor von Ahn bought the building which he extended towards the Ume River. Nowadays the building is owned by Umea Energi, whose headquarters are located between Von Ahnska magasinet and Gamla bankhuset.
