Your author tries to give a bit of variety with his suggestions, but sometimes the originals are the best. The Albert Memorial was commissioned by Queen Victoria in memory of her late husband Prince Albert, after his death in 1861. Designed by Sir George Gilbert Scott, it finally opened in 1872, but the seated statue of Albert, by John Henry Foley, wasn't added until 1875.
The huge memorial has a range of features including allegorical sculptures at each corner, depicting the Victorian industrial arts and sciences - agriculture, commerce, engineering and manufacturing - and the Victorian continents - Europe, Asia, Africa and The Americas.
