Researchers also found several royal utensils for the monarch's personal use, including water pots, betel-nut sets, trays, and boxes. The crypt also contained various ornaments, such as necklaces, bracelets, bangles, and rings. Royal clothing, unfortunately, except for the pieces woven in gold thread, disintegrated on contact with air when the "archaeologists" tried to remove it.
A second room houses an exhibition of golden offerings discovered in situ in the crypt of the principal Prang tower of Wat Maha That, where a golden reliquary containing the Lord Buddha's relic was enshrined. Wat Maha That was the first temple the FAD excavated in 1957 CE, thanks to funding from the Phibun Songkram Government and the establishment of a "Committee of Restoration of Ayutthaya" in 1956 CE. In August 1957 CE, archaeologists discovered several golden objects on the site. Workers found, in the main chamber of the principal prang, a solid gold lion half-buried in sand beneath the pagoda's pedestal, in a fish-shaped container decorated with a gilded motif and filled with other gold accessories.
Later, a shaft was found containing a hollow stone pillar, 3.20 m high, with a lid, buried in a cemented-brick pedestal. The container was filled with a small stupa wrapped in a lead sheet containing relics, gold ornaments, a large quantity of bronze images, pewter votive tablets and other valuables. See: "The Buddha Relics".
The balcony exhibits votive tablets and plaques made of terra-cotta and pewter (an alloy of tin and lead, lined with copper) from the Sukhothai, Lop Buri, and Ayutthaya periods, discovered in the crypts of the Prang towers of Wat Ratcha Burana, Wat Maha That, and Wat Phra Ram.
The second building exhibits artefacts and objects from the 6th to the 19th century, covering the Dvaravati, Sri Vijaya, Lop Buri, Chiang Saen, Sukhothai, U-Thong, Ayutthaya, and Ratanakosin periods for comparative study. Important items include various Buddha images and images of the Bodhisattva Avalokitesvara, Ganesha, and others.
The third building is a traditional Thai house built in the middle of a pond, displaying household equipment and utensils from ancient Siamese daily life.
