Ny Vestergade 9 is an 18th-century building located across the street from the main entrance to the National Museum in central Copenhagen, Denmark.

Former owners include court painter Hendrick Krock, printmaker Hans Qvist, Royal Armourer Christian Kyhl and wholesaler Jacob Stilling-Andersen.

The house had probably been intended for his daughter, who had married his friend, Magnus Berg, a Norwegian wood carver,[2] but died a few months after the wedding.

Riegelsen, a merchant who was active in the Iceland trade and also owned a brewery, was from 1794 one of the City's 32 Men.

He sold it in 1738 when he as president of the new Royal Danish Art Academy was granted an official residence at Bag Børsen.

In 1867, he was a co-founder of C. F. Riedel & Lindegaard iron foundry and machine factory on Kingosgade in Vesterbro.

Vilhelmine Hansine Saabye (née Harberg), a widow, resided in one of the ground-floor apartments with her two children (aged 10 and 13).

Jens Nielsen, a workman, resided in the basement with his wife Anna Antoinette (née Jensen) and their five children (aged nine to 16).

[8] At the 1895 census, Riedel's widow had moved to Ordrup but was still the owner of the property in Ny Vestergade.

Ny Vestergade 9 was in 1918 sold to Jacob Stilling-Andersen, founder of the Danish Butter Export Union.

A two-bay central gateway opens to a narrow courtyard flanked by two side wings.

[11] A relief of two crossed pistols on the keystone above the gate dates from royal gunsmith Christian Vilhelm Wilcken Kyhl's years as owner in 1797.
