'Fronalpstock' was the access door from an apartment to the attic floor in the Immenfeld manor house. Due to the relocation of the old staircase, it has now become available. The special thing about this fir wood door with cassette look is not only the good condition even after more than a hundred years (approximately 1912) but also the much older, functioning lock (approximately 300 years old). A charming addition is the heart fitting with keyhole and matching key.
