In a gold robe, gold embroidered pants, and a gold 7.3-kilogram (16-pound) crown, King Maha Vajiralongkorn is granting an audience to key Thai leaders.
Officials are offering their best wishes as the newly crowned King sits elevated on his ornate gold throne, flanked by men holding gilded fans.
Members of the Royal Family, the Privy Council, and the Cabinet, as well as senior officials, have all gathered in the lavish Amarindra Vinicchaya Throne Hall at the Grand Palace in Bangkok.
Thailand's King Maha Vajiralongkorn ascended the throne after his father's death in 2016 -- so why is he only just getting crowned?
The almost three-year gap between the late King's death and the coronation ceremony isn't unusual, said Thitinan Pongsudhirak, a Thai political scientist at Chulalongkorn University in Bangkok. King Vajiralongkorn needed time to grieve his father and prepare for the event.
"The official enthronement will solidify kingship and enhance his aura as the new king," said Thitinan.
King Vajiralongkorn won't get any significant additional powers, but he will now be seen as a fully-fledged King.
Prior to his coronation, King Vajiralongkorn sat on a throne beneath a seven-tiered umbrella, but he's now become the only person in Thailand permitted to sit on a on a throne beneath a sacred nine-tiered umbrella, which represents the King's connection with heaven.
