Huge crowds of black-clad mourners from across the country poured into Sanam Luang on Saturday morning, hoping to join the mass singing of the Royal Anthem in the afternoon and express their love for His Majesty King Bhumibol Adulyadej.
People holding umbrellas in the scorching sun strolled on the huge ground, waiting for the mass singing to start at 1pm. There were long lines for free food and drinks provided by hundreds of well-wishers.
Thousands of mourners also waited in front of the Grand Palace's Viset Chaisri Gate, waiting for their turn to sign the condolence book in the Sala Sahathai Samakhom Pavilion inside the compound.
People coming to Sanam Luang are required to go through many security checkpoints set up around the ground.
