In 1959 Karsten and Ellen married and
started their family. While on subsequent
family vacations in Door County, they fell
in love with the Wisconsin peninsula’s
rugged beauty. In 1971, they purchased the
historic Larson Rooming House in Ephraim,
transforming it into the Hanseatic Art
Gallery and opening it to the public in 1972.
In the heart of Ephraim, a historic former rooming house
built by the Ephraim founding Moravians in 1900, the
Hanseatic Art Gallery offers oil paintings, watercolors
and acrylics by Karsten Topelmann and Ellen Sprogø-
Topelmann in a variety of formats and subject matter.
For over 45 years, they have welcomed art lovers and
have sold to customers and collectors all over the US and
abroad. Sadly Ellen passed away in August of 2016, but
Karsten is still painting actively and running the gallery.
The name Hanseatic originates from Ellen’s birth city
Hamburg, Germany. Hamburg was a major port and an
imperial city in the Hanseatic League, a trading alliance in
Northern Europe between the 13th and 17th centuries.
Framed prints of art work in numerous sizes as well as
boxed greeting and Christmas cards are available.
In-house framing allows for individual mat color and
