The entire village of Erschmatt is designated as part of the Inventory of Swiss Heritage Sites.
In 2013 Herbert Lötscher built the world's first residential Heliodom or sun house concept.
 The house is designed so that during the winter the large windows allow the sun to heat the entire building, while in the summer they are shaded and cooled.
 The design allows the Heliodom to consume up to 80% less energy than a comparable standard home.
