Thousands of mourners dressed in black have lined the streets of Bangkok and assembled at viewing areas across Thailand for the elaborate funeral ceremonies of King Bhumibol Adulyadej.
Two large video screens were set up near a replica of the royal crematorium near the King Rama V monument in Bangkok - one of nine replicas in the city.
A total of 85 replicas were built nationwide for those who could not travel to the capital to witness the cremation ceremony.
Some mourners were in tears as they watched Buddhist monks and current King Maha Vajiralongkorn take part in prayer rituals inside the Dusit Maha Prasat Throne Hall ahead of the sombre processions to the crematorium.
Members of Thailand's royal family then led the two-kilometre (1.2-mile) procession to the site of his specially built crematorium, next to the Grand Palace in Bangkok, joined by Thailand's junta leader and Prime Minister Prayuth Chan-Ocha.
An urn meant to symbolise Bhumibol's remains was placed upon a golden chariot, used to carry the urns of royal family members dating to the start of the Chakri dynasty.
As the chariot, pulled by hundreds of men in traditional red costumes, passed the mourners lining the parade route, they prostrated themselves, pressing their folded hands and head on the ground in a show of reverence for the late monarch.
The chants of monks mixed with the beat of royal drummers as it arrived at the cremation grounds, while the sound of artillery could be heard fired in the distance and a band played songs composed by the late king.
Bhumibol's remains will be cremated on Thursday evening within the golden-spired crematorium, which was built over a year and represents mystical Mount Meru, where Buddhist and Hindu gods are believed to dwell.
Deceased Thai royals have traditionally been kept upright in urns during official mourning. But Bhumibol, who spent much of his early life in the West, opted to be put in a coffin, with the royal urn placed next to it for devotional purposes.
Bhumibol's death at the age of 88 on October 13 2016, after a reign of seven decades, sparked a national outpouring of grief and a year of mourning. Millions of Thais visited the throne hall at Bangkok's Grand Palace to pay respects.
The adulation Bhumibol inspired was fostered by palace courtiers who worked to rebuild the prestige of a monarchy that lost its mystique and power when a 1932 coup ended centuries of absolute rule by Thai kings.
He was also genuinely respected for his development projects, personal modesty and as a symbol of stability in a nation frequently rocked by political turmoil, though his influence waned in his final years.
The funeral is by design an intensely sombre event, but also rich in history and cultural and spiritual tradition.
Boonjerd Buasawat, a 61-year-old fruit vendor from the resort island of Phuket, had been waiting near the cremation site since midday on Wednesday and slept there overnight.
"I want to be here together with a group of people who dearly love their king," he said. "Our love won't die until we too pass and follow him."
