King Rama III Memorial

Mahakan Fort is one of only two remaining forts of Rattanakosin's outer city walls, the other being Phra Sumen Fort near Khao San Road. Mahakan Fort is on the banks of Rop Muang Canal, and a part of the former ring of forts that defended Rattanakosin Island from invasions from the east. It was built during the reign of King Rama I. What makes this fort unique compared to Phra Sumen Fort is that a part of the old city wall is still intact; it runs about 200 metres south along Maha Chai Road. An almost a century old community lives in shanties between the old city wall and the canal, but the Bangkok Metropolitan Administration has been trying to turn it into a public park for tourists (as was done around Phra Sumen Fort). After a 14-year legal dispute, it seems like a compromise has been reached where some houses of the old community will stay and be turned into museums.

Wat Ratchanaddaram is a temple compound built by order of King Rama III in 1846. Its main structure, Loh Prasat (โลหะปราสาท, Thai for metal castle), is easily spotted as its spires are of black iron, not the usual glittery gold. It is in a highly unusual style: the wat itself is a five-storied gleaming white structure with rows of Buddhas and nice views from up top, very elegant, calm and relaxing after the crowds at the big temples. A good view of Bangkok is afforded from the top tier. The 37 metal spires signify the 37 virtues towards Enlightenment. At night, the square around it is beautifully illuminated. Also check out the Buddhist market at the rear of the complex.

This privately funded gallery was established after the request of HM Queen Sirikit who wanted a permanent venue for the exhibition of Thai arts. The gallery has four floors of contemporary and modern arts, including paintings, sculptures, audiovisual arts and even furniture arts, most of them created by students. Many paintings use elements of traditional Thai life and religion and place them in a contemporary setting. Taking pictures without using the flash is allowed. There is also a reading room and a café.

The building is designed by the French-Swiss architect Charles Beguelin in 1906 in a neo-classical style that popular with King Rama VI and King Rama VII. It was renovated by the King Prajadhipok Institute to serve as a museum exhibiting a rare collection of King Rama VII's personal belongings, including photographs, documents and his biography. King Rama VII ruled in a turbulent time of Thailand's history; he was the last King who enjoyed absolute monarchy, as well as the first King under a constitutional monarchy. Significant events and stories relating to King Rama VII are exhibited, including his succession to the throne, royal activities, political reform, promulgation of the constitution, royal utensils and memorabilia, as well as his life after abdication and death in the United Kingdom. The demolished Sala Chaloem Krung Theatre that used to stand in the nearby area is imitated with old films being projected.

The temple was built in 1836, during the reign of King Rama III. Like other temples from the third reign, it has a Thai layout, but is combined with a mixture of Chinese architectural styles. The gables are decorated with Chinese porcelain pieces and there are Chinese statues all over the complex. Unfortunately, the temple is in desperate need of renovation. Sunthon Phu, one of Thailand's greatest poets, resided in this temple during his monkhood in the early 1840s. The quarters where he spent three years of his life are preserved at the rear of the compound, and might be turned into a museum. In 1986, UNESCO declared Sunthon Phu one of the world's greatest poets.

Wat Saket was built outside of the former city walls in the late 18th-century in the reign of King Rama I. It served as the capital's crematorium, and throughout the next century became the dumping ground of over 60,000 plague victims who were too poor to afford a funeral. Wat Saket's major feature is the Golden Mount, an artificial hill dating from the early 19th-century. A huge chedi was built on top of the hill in the reign of King Rama III, but it collapsed during the construction process as the soil was too soft to support it. King Rama IV used a 1,000 teak logs to secure the mound and started construction on a more modest chedi that still exists today. Later, King Rama V chose the chedi as the place to inter relics of the Buddha that had been discovered among the ruins of Piprāwā, India and presented to him by the British Government. A spiral staircase of 318 steps leads from the ground to a terrace and shrine-room — the Buddha's relics are housed in a gold-leaf-covered shrine at the centre of this area. In the first week of November, the mount is illuminated with coloured lanterns and the compound turns into a large fun fair.
