Straddling the Chao Phraya River and situated just north of Chinatown, Koh Rattanakosin - the old city - is where you'll find Bangkok's most spectacular and revered historical attractions. Not only part of the Kingdom's rich past, but intrinsic to it, with shimmering, spire-shaped eye-candy on nearly every corner.
A very unique structure in the Bangkok skyline is the Wat Ratchanatdaram Worawihan (formerly Wat Ratchanadda), a Royal temple best known for the Loha Prasat. The Loha Prasat, which means iron castle or iron monastery, is a 36m high and has 37 black metal spires symbolizing the 37 virtues that are required to reach enlightenment. You can climb the spiral stairs to the top of the structure. Just below the shrine on top is an open air walkway from where you will have a good view of the temple area, as well as the Wat Saket temple and the Golden Mount. The Loha Prasat of Wat Ratchanatdaram Worawihan is the only one of its kind in existence today and thus under consideration with UNESCO to be made a World Heritage Site. A short walk brings you to Wat Thepthidaram, also known as Temple of the Heavenly Daughter, unique because it contains images of female disciples of Buddha. It was King Rama III who established this temple in 1836 for his oldest favorite daughter. The exquisite designs in this temple constitute the four directional Stupas created by court artisans and the mural paintings on the walls of the main temple. Wat Saket is easily recognized by its golden Chedi atop a fortress-like hill. The Golden Mount houses relics of Lord Buddha and affords visitors who climb its 318 steps a panoramic view of old Rattanakosin and the roofs of Bangkok from the top.
For lunch we proceed to Methavalai Sorndaeng - a traditional Royal Thai Cuisine restaurant with retro classy atmosphere and located at the majestic circle of the Democracy Monument.
After satisfying your hunger, continue to the Jim Thompson's House & Museum. Hailed locally as the 'father of Thai silk', he was an avid collector of Thai art and antiques. His house, comprising six lovely teakwood homes acquired from Ayutthaya and Bangkok's Baan Krua community, is an unparalleled example of the East meets West style, well before its time. A profusion of rare art pieces, antiques and exquisite interior details speak of his ingenious ability to 'bend' tradition - in a positive way - and create something completely his own.
