Tonle Bassac, once a quiet neighborhood in Phnom Penh, has undergone a remarkable transformation over the years, evolving into one of the capital’s most prestigious and vibrant districts. It is part of Chamkarmon district, located on the west side of the Bassac River, circled by Sihanouk Blvd. and Norodom Blvd. Just across the Bassac River lies Koh Pich (Diamond Island), a newer extension of the district that’s gradually become a vibrant part of Tonle Bassac’s ongoing story—home to modern developments, event spaces, and waterfront attractions.
With a combination of modern high-rise buildings, lush green spaces, and historical landmarks, Tonle Bassac has emerged as a symbol of Cambodia’s rapid development and urbanization. The area’s growth has been fueled by the influx of foreign investments, driving the construction of luxury real estate and commercial projects that have reshaped its skyline and attracted both locals and expatriates.
