The CIA built one of its secret European prisons inside an exclusive riding academy outside Vilnius, Lithuania, a current Lithuanian government official and a former U.S. intelligence official told ABC News this week.
Where affluent Lithuanians once rode show horses and sipped coffee at a café, the CIA installed a concrete structure where it could use harsh tactics to interrogate up to eight suspected al-Qaeda terrorists at a time.
"The activities in that prison were illegal," said human rights researcher John Sifton. "They included various forms of torture, including sleep deprivation, forced standing, painful stress positions."
Lithuanian officials provided ABC News with the documents of what they called a CIA front company, Elite, LLC, which purchased the property and built the "black site" in 2004.
Lithuania agreed to allow the CIA prison after President George W. Bush visited the country in 2002 and pledged support for Lithuania's efforts to join NATO.
"The new members of NATO were so grateful for the U.S. role in getting them into that organization that they would do anything the U.S. asked for during that period," said former White House counterterrorism czar Richard Clarke, now an ABC News consultant. "They were eager to please and eager to be cooperative on security and on intelligence matters."
Lithuanian president Dalia Grybauskaite declined ABC's request for an interview.
ABC News first reported that Lithuania was one of three eastern European countries, along with Poland and Romania, where the CIA secretly interrogated suspected high-value al-Qaeda terrorists, but until now the precise site had not been confirmed. Read that report here.
Until March 2004, the site was a riding academy and café owned by a local family. The facility is in the town of Antaviliai, in the forest 20 kilometers northeast of the city center of Vilnius, near an exclusive suburb where many government officials live.
In March 2004, the family sold the property to Elite, LLC, a now-defunct company registered in Delaware and Panama and Washington, D.C. That same month, Lithuania marked its formal admission to NATO.
The CIA constructed the prison over the next several months, apparently flying in prefabricated elements from outside Lithuania. The prison opened in Sept. 2004.
According to sources who saw the facility, the riding academy originally consisted of an indoor riding area with a red metallic roof, a stable and a cafe. The CIA built a thick concrete wall inside the riding area. Behind the wall, it built what one Lithuanian source called a "building within a building."
On a series of thick concrete pads, it installed what a source called "prefabricated pods" to house prisoners, each separated from the other by five or six feet. Each pod included a shower, a bed and a toilet. Separate cells were constructed for interrogations. The CIA converted much of the rest of the building into garage space.
Intelligence officers working at the prison were housed next door in the converted stable, raising the roof to add space. Electrical power for both structures was provided by a 2003 Caterpillar autonomous generator. All the electrical outlets in the renovated structure were 110 volts, meaning they were designed for American appliances. European outlets and appliances typically use 220 volts.
