Bangkok: Chakri Memorial Day, observed annually on April 6th, commemorates the ascension of King Rama I to the throne and the founding of the Chakri Dynasty. This day marks the establishment of Krung Thep Mahanakhon Bowon Rattanakosin, now known as Bangkok, as the new capital city. The transition from Thonburi to Bangkok in 1782 initiated what is referred to as the Rattanakosin era, a period that has seen nine successive monarchs over the past 234 years.

According to Thai News Agency, historical records show that in 1873, King Chulalongkorn commissioned the creation of statues representing the first four monarchs of the Chakri Dynasty. These statues were initially housed in the Dusit Maha Prasat Throne Hall for annual homage but have since been relocated. During King Vajiravudh's reign, the statues were moved to Thep Bidon Palace within Wat Phra Sri Rattanasasaram, alongside a statue of Rama V. This relocation was completed in 1918, and King Vajiravudh subsequently established April 6th as Chakri Day, a day for official ceremonies to honor past monarchs.

On this public holiday, His Majesty the King, joined by the Royal Family, leads religious ceremonies at the main chapel and pays respect to the statues at Thep Bidon Palace. The day also includes the laying of a wreath at the monument of King Rama I at the Phra Phutthayodfa Bridge.

Chakri Day is a significant occasion for all Thais, with participation from the Prime Minister, senior government officials, and citizens from various sectors. They gather to lay wreaths and engage in religious rites, honoring the legacy of the Chakri Dynasty. The government has declared Chakri Day a public holiday, with provisions for a compensatory day off if it falls on a weekend.
