Eckhart Druse raised the back building (now The Green House) from where he ran his antique business.
This house was mainly constructed of medieval bricks that Eckhart Druse obtained from the rebuilding of the corner property Brogade/Torvet.
In 1962, Eckhart Druse bequeathed No. 1, 3 and the villa in the backyard to Køge Municipality with the proviso that operating profits are to be given as scholarships to Køge High School.
Rebuildings have taken place later, probably several times. And in 2013, the property was given a major lift with a total replacement of the over 100-year-old floor construction on the ground floor.
After the most comprehensive rebuilding of 3 Vestergade in this century, the ground floor appears today more elegant than ever before.
