Hans van Steenwinckel the Younger (24 June 1587 – 6 August 1639) was a Flemish-Danish architect who specialised in the Dutch Renaissance style, typical of prestigious Danish buildings from the first half of the 17th century.
Back in Denmark, Hans and Lorenz van Steenwinckel would become involved in most of Christian IV's numerous huge building projects in the first decades of the 17th century, though it is often not clear exactly what their share was.
In the same time large prestige buildings were far from static entities, rather it was normal for them to see numerous extensions and reconstructions, developing gradually over the years.
To make matters even less clear, it was a strategy of Christian IV, and possibly his advisors, to keep the authorship of a building hidden to suggest that king himself was the author.
After Lorenz' death in 1619, Hans was appointed new Royal Master Builder, and took over ongoing projects, such as Christian IV's Chapel at Roskilde Cathedral, under development since 1613, and the newly commenced Stock Exchange in Copenhagen.
