Venezuelan skyscraper, home to 3,000 squatters, is one tall slum

Caracas: It boasts a helicopter landing pad, glorious views of the Avila mountain range, and large balconies for weekend barbecues. Yet this 45-storey skyscraper in the center of Venezuela's capital Caracas is no five-star hotel or swanky apartment block: it is a slum, probably the tallest in the world.

Dubbed the "Tower of David", it was intended to be a commercial centre but was marooned.

Squatters seized the huge concrete skeleton in 2007, then-President Hugo Chavez's socialist government turned a blind eye, and now about 3,000 people call the tower their home.

Though many residents view it as a den of thieves and a symbol of rampant disrespect for property, residents call the "Tower of David" a safe haven that rescued them from the capital's crime-ridden slums.

It appears - at least for now - to have escaped the violence and turf warfare that followed similar building takeovers in Caracas over the last decade, often launched under the banner of the late Chavez's self-styled revolution.

Communal corridors are freshly-polished, rules and rotas are posted everywhere, and non-compliance is punished with extra "social work" decided by a cooperative and floor delegates who make up a mini-government.

"Without ethics or principles, all is irrational," reads one typically didactic poster in a public area.
