Muntinlupa is a town south of Manila. Among the locals, it is most known for having the country's most famous prison, the Bilibid Maximum Security Prison, where some of the country's high profile and dangerous criminals are held. However, the Filinvest Development Corporation and Ayala Land have started work on building two business districts for the city that will offer firms an alternative location to Makati City and Ortigas Centre for their operations. Insular Life, one of the country's largest insurance firms, has recently moved their corporate headquarters from Makati City to their new Insular Life Towers in the Filinvest Corporate City. Only time will tell whether Muntinlupa will have the same success as a business center and a mecca for skyscrapers as Makati City and the Ortigas Centre have been.
