The Hermannsdenkmal (in memory of Arminius' victory at the Teutoburg Forest) was riddled with bullet holes (click on the picture to enlarge) by passing Allied planes. I suspect that was more a case of "celebratory gunfire" than the result of any planning though.

The letter quoted on this page mentions that the statue was "bombed but not hit", but the writer did not witness the attack ot it's aftermath himself, so a dose of salt is warranted.

Much as the London blitz shifted focus from airfields to the city after the RAF bombed Berlin in 1940, following the bombing of Lübeck and Rostock in 1942 the Luftwaffe conducted a series of retaliatory raids, known as "Baedeker Raids" after the famous German Baedeker tourist guides. These Baedeker targets remained on the German list until the end of the war, including countryside market towns with minimal military significance.

As /u/sacamato notes, due to the limitations of technology where these raids were successful, it was more by luck than good judgement. Wikipedia notes that the York Guildhall and Bath Assembly Rooms were both destroyed, but that a number of notable cathedrals were unscathed: https://en.wikipedia.org/wiki/Baedeker_Blitz

No, British landmarks never specifically aimed to bomb the Nazis.
