The People of Gibraltar
1850 - William J. Huggins - The Other Huggins

William John Huggins was a well known an artist who became a marine-painter to both George IV and William IV.

However . . . it would seem from a comparison of their respective styles that the pictures of Gibraltar shown below are not by this Huggins but by another artist with the same name. 

Unfortunately no amount of research on my part has been able to uncover any information about this gentleman other than that he was born in 1781 and died in 1884. The pictures shown below seem to have been painted around the middle of the 19th century. 

View of Gibraltar from Spain - perhaps the road to San Roque

View of the East Side of Gibraltar
There is a hint of a lighthouse on Europa Point on the left. If it is it would date the painting as post 1841 which is when it was inaugurated

View of the "Sugar Loaf" from the South
The house is Governor's Cottage and the road to the right leads to Europa Advance Battery - the tower at the top of the "Sugar Loaf" is O'Hara's Folly  - (See LINK)

View of the Line Wall and Rosia (See LINK)
There are two ships in Rosia Bay harbour and the nearby Rosia Water Tanks (see LINK) - is the large building just to the left of the Bay - although I always thought they were two stories high rather than three.  On the right in the far distance is Bleak House (See LINK)

View from near Rosia looking North
An odd view in that the rather flamboyant house in the foreground is hard to identify. The area to left showing the head of a grazing donkey could be an area known as the Devil's Bowling Green
