Since rampaging mobs broke down the gates of Government House on Aug 26 as part of their campaign to topple the government, they have set up a festival-like tented city on the once-manicured lawns.
At its height, tens of thousands of supporters of the People's Alliance for Democracy (PAD) were camped out, causing a massive pile-up of rubbish and a smelly shortage of portable toilets.
Now, they are flooding out of the doors and into pick-up trucks, to head to the PAD's new protest sites at Suvarnabhumi international airport and the smaller Don Mueang hub, which they seized last week, paralysing air travel.
'I will miss it,' said 63-year-old Wan Ounkonc as she washed dishes and packed away a kettle, readying for her journey to Don Mueang. 'I would like to stay here. I know many people here and I got used to where I sleep.'
PAD leaders say they are moving because of a spate of grenade attacks on the Government House compound. Emergency services said 49 people were injured when unknown attackers lobbed a grenade at the site on Sunday.
Similar attacks last month killed two protesters, and prompted PAD leaders to call for a 'final battle' in their six-month bid to topple the government, which it accuses of being a puppet of ousted premier Thaksin Shinawatra.
'We believe the attacks will happen more and more so we are going to seek a safer place,' said housewife Noo Hinon, 50.
She said she had not decided yet which airport to set up camp at, but added: 'Wherever I go, I will fight for the nation.' Protest leaders have called on their supporters to reinforce the positions at Suvarnabhumi and Don Mueang, which are taking on the same aura of permanence that has until now prevailed at Government House.
In front of the main Venetian-style main building where ministers used to meet and greet dignitaries, protesters had set up food stalls and massage services, while every night leaders would give rousing speeches on a stage.
Rapturous PAD loyalists - most dressed in yellow to show their allegiance to the monarchy - would cheer and frantically wave noisy plastic handclappers.
Thai country bands would also deliver rousing songs in the evening to lift the spirits of protesters.
On the darker side, PAD militia members, who police said are armed, patrolled the perimeter, where they set up barricades of razor wire and tyres.
At least two people have been shot outside the compound after arguments with the menacing PAD volunteer guards.
People began dismantling the stages and televisions screens on Monday, while others carried chairs, tables and electric fans out of the gates.
'I will go to Suvarnabhumi,' said one woman with a suitcase in one hand and a camping chair in the other. 'This place is not safe so I don't want to stay.' -- AFP
