The house was built approximately in the year 1700 in an area that was reserved for the nobility in the city plan made up by Per Brahe the Younger in 1652.

Today, the Qwensel House operates as the Turku Pharmacy Museum and café.

The exhibition wing of the building has Åke Lydman's collection of pharmacy utensils on display.

The use of pharmaceutical herbs can be studied with the lead of an "apothecary" at the Children's Pharmacy, the courtyard and outdoors.

The former stable, toilet and barn are located at the northern end of the Pakaritupa wing of the building.
