Phra Sumen Fort is strategically positioned along the banks of the Chao Phraya River, near the intersection of Phra Athit Road and Phra Sumen Road. It was built during the early 19th century during the reign of King Rama I, as part of a defensive strategy to protect the city against potential naval invasions.
The fortress features a traditional Thai architectural style with its distinctively shaped battlements and crenellations. The design reflects a blend of both practical defensive features and aesthetic elements. The fortress is characterized by its white exterior, intricate decorations, and eye-catching spires.
Phra Sumen Fort played a vital role in safeguarding the city from potential river-based threats. Its position along the river allowed it to serve as a key defense point, with cannons aimed at protecting Bangkok’s waterways.
The fortress is part of the old city wall that once encircled Bangkok. While much of the original wall is no longer standing, the remaining portions, along with Phra Sumen Fort, provide valuable insights into the city’s historical layout and fortifications.
Adjacent to the fort is Santichaiprakan Park, a green space where locals and visitors can relax, exercise, or take in views of the Chao Phraya River. The area has a relaxed and artistic atmosphere, making it a pleasant place for a leisurely stroll or to enjoy local cuisine.
Consider visiting in the late afternoon or early evening to witness the sunset over the Chao Phraya River and experience the area’s vibrant nightlife.
