Klosterstræde 21

Klosterstræde 21 is a historic four-storey building located in the Old Town of Copenhagen, Denmark, completed in 1817. It has been home to a glazier's business since its inception, currently operated by H. P. Olsen & Søn, which has adorned the building with unique antique stained glass windows. The site has a rich history, originally comprising two properties that were merged after the Copenhagen Fire of 1728. The building showcases a blend of architectural styles with a grey ground floor and undressed red brick above, featuring a charming courtyard. Listed as a protected building since 1950, it offers a glimpse into Copenhagen's past and is a notable stop for tourists and researchers interested in the city's architectural heritage.
