The pavilion was built by architect Olof Tempelman – with detailed instructions from the highly-engaged King Gustav III. Yet another great artist was commissioned for the interiors – Louis Masreliez – who became a trendsetter in the interior design of the period.
The interiors of the Gustav III Pavilion can be viewed during the summer months when the pavilion is open for guided tours.
The pavilion was just one of many great plans and visions that Gustav III had for Haga Park, many of which made it no further than the drawing board.
Gustav III made use of the pavilion for a few years before his assassination. It was from here that Gustav III left for the fateful masquerade ball at the Opera in March 1792.
