Wasserturm
Wasserturm (Water Tower), an octagonal tower built next to the Kapellbrücke in Lucerne. Built ca. 1300 before the Kapellbrücke. It was intended as a defensive tower facing Lake Lucerne and has been a prison, archive and gift shop.
"Adjoining the Kapell-Brücke, in the river, rises the old Wasserthurm, containing the Municipal Archives. According to tradition, the building was once a lighthouse (lucerna) and gave its name to the town".--Baedeker 1903.
