Dreamsbolts, my first fort to reach all the requirements for becoming a Mountainhome (although I have to wait another year for the caravan) has a lot of very carefully placed statues.
The corridor leading to the wells is decorated with a dozen statues of dwarves dying of dehydration. Just so you REALLY appreciate that drink of water.
The hospital is decorated with statues of the doctors, and dwarves dying of horrible diseases and injuries.
The west cloister of the throne room has statues of the expedition leader, mayors, the baron, etc. The east cloister celebrates the accomplishments of the common dwarves. Mostly statues of the creation of artifacts and striking down dangerous beasts.
The sheriff's office had statues of most of the past sheriffs, and dwarves being beaten or struck down for tantruming.
The trade depot has a masterwork statue of the god of fortresses, steel, forges, and booze, depicted as a female dwarf, laughing.
The baron's tomb has a statue of the foundation of Dreamsbolts, and an artifact statue of the Queen.
The atriums in the middle of the residential blocks have statues of local megabeasts.
There are a few other ones. The Stonemaster (legendary engraver and mason) has a few statues of himself, the manager has a statue in his office of himself terrified surrounded by fire imps, and that's all I can remember.
Oh yeah, 95% of these are all made by the same dwarf. I wish I had more marble, I don't want to use it up cranking out endless statues so I mostly use mica and gneiss.
