Puerta Secreta Bukammun is a concealed gate on the northern section of Hwaseong Fortress's defensive wall. This lesser-known entrance provides access to a picturesque pond area with panoramic views across the fortification. Located in Suwon, it offers visitors a quieter alternative to the main entrances whilst affording excellent vantage points of the fortress grounds. The gate remains an intriguing historical feature that rewards those venturing beyond the well-trodden paths.
