The Chakri Maha Prasat is located on what used to be a garden, and was later the house of King Rama V's mother in which the future king was born and raised. The base of the building houses the royal guards and a collection of ancient weapons is displayed in the arcades along the building's front. This display is open to the public on weekdays only. On Saturday and Sunday, you can see some of the exhibits through the bars, but there's no entry to see things close up.
