A quick note on obelisks, as I see the one in the background of the painting is described as an ‘unlikely architectural feature’.

I don’t think this is quite right.  Obelisks were, in fact, rather common in northern architecture of the period, featuring regularly in formal gardens.  For example, Robert Dudley’s garden at Kenilworth(visited by Elizabeth I in 1575) was divided into four quarters, each of which had an obelisk in the centre, “rising pyramidically fifteen feet high” with an orb “of porphyry” on the top.  So, we shouldn’t be surprised that the garden in the background of the Linder gallery contains such a feature.  It may have been modeled on one of Hans Vredeman de Vries’s popular and widely circulated designs, an example of which is shown below.  We can also see, in this painting by Vredeman de Vries, a configuration of balcony, staircase, and obelisk more or less identical to the configuration of the Linder galleryRIJK01_M-SK-A-2390-00_X.JPG.
