The Springfield Retirement Castle, built in 1929, sometimes called Springfield Retirement Home, is a location located at 2001 Creaking Oak Drive. It is Springfield's retirement home for the elderly.
The staff of the care home couldn't care less for the people they are supposed to be looking after and make as little effort as possible to ensure the health and happiness of them, doing things like vacuuming their hair during "nap time", or switching their IV sacks with their catheter sacks when the former is empty and the latter is full.

Volunteers like Lisa or Bart sometimes come to help seniors and less-caring adult staff. On occasions, there are good hearted staff members.
