"After a 14-month, $75-million renovation, the Compaq Center will reopen as Lakewood Church, the nation's largest house of worship... Requiring arena-sized seating and vast parking lots, these churches are expensive to build and demand large plots of land that are difficult to come by in urban areas. That has made rejected sports arenas, faced with demolition, fertile ground for religious conversion... As the new generation of sports facilities has sprung up, the megachurch defined as any with more than 2,000 worshippers has flourished."
