The hermitage as a place of solitary retreat occurs from antiquity to the late nineteenth century because it appealed to people in different periods and could be easily adapted to the specific wishes of the noble, religious or intellectual owner and the taste of the age. This article presents new research into the hermitage on Dutch country estates, based on an analysis of for sale notices, primary source research (mainly travellers’ tales) and a review of the literature.

Thanks to this new, larger data set it was possible to make more accurate statements about the period in which the hermitage was popular, about its distribution in the Netherlands, its location in the garden, its appearance and its significance. A search through digitally accessible newspapers led to the discovery of many slightly later, smaller hermitages. And whereas Gelderland had previously been regarded as the foremost hermitage province, in light of current knowledge that perception has now swung in favour of Holland. This has also served to accentuate the bourgeois character of the hermitage: it was most prevalent on the country estates of urban regents, located close to the city.

Evidence suggesting that the hermitage design was highly standardized can also be found in descriptions of hermit’s huts in travel reports. Contrary to what is often assumed, the popularity of the hermitage suggests that the Dutch ...
