The Fine Arts Department hoped the makeover would bring about good luck and stability for the country.

Department director-general Arak Sanghitkul said work had started on the two pillars, five goddess sculptures, the mural and landscaping. The work is being subsidised by the Veterans General Foundation.

In 1782, King Rama I had the first City Pillar erected in front of the Grand Palace during the construction of Bangkok as the new capital of Siam. The City Pillar Shrine was reconstructed by King Rama IV.

Arak said the centuries-old pillars had become dilapidated.

Gilding on the eldest pillar had become dirty and the second, last restored 20 years ago, had been rotted by humidity.

"The pillars might suffer more severe damage if they are not urgently repaired," said Arak, adding they would be dried and re-lacquered before new gilding was applied.

The work will be finished by February and is another project marking the 60th anniversary of His Majesty the King's accession to the throne.

The City Pillar Shrine is a sacred Bangkok landmark. People believe the pillars have made the nation safe and the goddesses residing there guard people and guarantee a pleasant life.

"The renovation of the City Pillar Shrine is believed to create good luck and bring an end to unpleasant situations," said Arak.

People will be allowed to pay homage from outside the shrine.
