Altona was built by Jens Drejer and for many years Henningsværs’ only shop was in this building. And as the sole shop, a substantial storage was needed. The building contained a living area too.
After the death of Drejer the building was sold and has had several owners down the years. Best known of these is Ingvald Ramberg.
In 2005 Altona was rebuilt, constructing within its walls a number of flats. Henningvær embraces development, carefully tempered with maintenance of the historical appearance and feel of the village.
