The IM-455 modular garrison, also known as The Peacekeeper, was the Empire's standard base deployed on planets to keep the peace and serve as a home for its troops. It was built by Rothana Heavy Engineering as a rewarded manufacturing contract, and its main purpose was to allow an Imperial Army commander to achieve the same results of turning a venerated political/religious structure into the seat of power for the Empire on a world and at the same time allow for optimized defense. A standard Imperial garrison is elevated for observation, angled for defense, and acts as a symbol to Rebellious populations that the Empire isn't going anywhere.
