The only hills in our area are the reminders from the coal mining area, the former pithead stocks.
Most of them are recultivated and some are changed into parks now, with platforms for sightseeing and landmark sculptures on top.
Like this one next to my home, a (yellow) steel sculpture which is illuminated at night.


For other 'landmark architecture' in this week´s challenge, have a look here:
