The drawing is inverted relative to the sketchbook’s foliation. It shows what is now the Timeball Tower Museum,1 set back a little from Deal’s seafront off Victoria Parade. Before the timeball mechanism was established to assist accurate navigation in 1855, between 1821 and 1831 there was a semaphore mast, as apparently shown by Turner, used for anti-smuggling operations, on the site of a Napoleonic-era shutter telegraph.2 There is another view in the 1825 Holland sketchbook (Tate D19389; Turner Bequest CCXIV 277).
