This watercolour of Glenbrook by the Irish painter John E Bosanquet was painted some time in the 1860s. Bosanquet is known to have been visiting Cork in 1863 and this seems the most probable date for the painting. The hotel and baths have been encircled in the above reproduction to indicate the position of the detail below.
This close-up of the hotel and baths does not seem to correspond with the description of the actual buildings at any specific time and it seems probable that Bosanquet intends only an impression of the buildings—and a rather romanticised impression at that.
