Looking up at the ‘Castle of the Moors’ on the crest of the hill above Sintra in Portugal. The 8th century castle was restored in 1840, at the same time that the nearby Pena Palace was being built, and its dramatic position makes it a key element in the highly picturesque scenery around Sintra.

Another quick sketch focussed on the boundary between sky and horizon, something that gouache seems to excel at.
