Thailand is planning construction of a 459-metre-high observation tower in Bangkok as the country's new landmark and tallest building.
The Thai cabinet has approved the construction of a tower estimated to cost 4.6 billion baht ($A178 million), but the timeline of the construction has not yet been determined, said government spokesman Sansern Kaewkamnerd.
'This will be Thailand's new tourism landmark' Sansern said, noting it will be 'without a commercial purpose.'
'There will be no shops and the profits made from entry fee will be donated to charity,' he added.
The towering structure, to be built near the bank of the Chao Phraya River, which runs through Bangkok, will mainly feature galleries showcasing social development projects initiated by the late king Bhumibol Adulyadej, who died in October and other things about Thailand.
The entry fee will be 750 baht for non-Thai visitors. The fee will be halved for Thai citizens, Sansern said.
Funding will be raised from private financial institutions and businesses and will not involve government budgets, he added.
When completed, the tower will surpass MahaNakhon, Thailand's currently tallest building, at 314 metres. It will also be Southeast Asia's second-tallest building, after Malaysia's Petronas Towers.
