This fort once formed part of a city wall built during the reign of Rama I. The wall headed east from here, reaching a canal that ran south and functioned as a moat. This effectively formed a protected island, and that’s why the neighborhood is still called Rattanakosin Island.
For years the fort was in disarray, but today the whitewashed octagonal structure stands proud beside Santichai Prakarn Park, across the street from some great restaurants and street food stalls. A couple of kilometers south is the country’s best art school, Silpakorn, whose students at one point helped renovate the fort.
