Groups of tall cypress trees and stone or umbrella pines were some of the natural features which characterised the landscape in this part of Italy, as described by Thomas Jones in the 1770s:
About Frescati, Albano, Castello, L’aricci, Gensano &c are to be seen Groves and Walks of the finest and most luxuriant forest Trees imaginable – The Ilex, Chessnut, Plane, Oak and Wallnut grow to an Amazing Size, to which we may add the Noble Pines & Cypresses which are planted in the Gardens & Vineyards. – The Waters of the two Lakes, still & transparent – reflect as in a murrour, the verdure of their shady Margins.1
The location for this sketch may be the wooded hills which separate Lakes Albano and Nemi. Turner travelled south from the former towards Ariccia, Genzano and Nemi. For a discussion of the inscribed date on this page see the general introduction to the sketchbook.
