Power couple, Brad Pitt and Angelina Jolie, have drafted plans to build an eco-friendly theme park for their six children. Located at their chateau in the South of France, the park is will be completely underground and covered by turf. Pitt and Jolie aim to make the playground completely environmentally-friendly, complete with a solar-powered rooftop and reusable water supply. The couple’s sustainable efforts is also present in Pitt’s “Make It Right Foundation” in which volunteers help build eco-friendly houses in New Orleans post Hurricane Katrina. Insiders say that the theme park idea came from a botched visit to Legoland last September, in which security concerns cut their trip short. The personal amusement park will feature a pool, castle, carousel, and a mini train that goes around the whole grounds. However, the general public will not be able to partake in the green fun.
