The City of Muntinlupa (Filipino: Lungsod ng Muntinlupa) is the southernmost city in Metro Manila. It is bordered on the north by Taguig City; to the northwest by Parañaque City; by Las Piñas City to the west; to the southwest by the municipality of Bacoor, Cavite; by the municipality of San Pedro, Laguna; and by Laguna de Bay to the east, the largest lake in the country. It is nicknamed the "Emerald City of the Philippines". According to the 2000 census, it has a population of 379,310.
Muntinlupa City was once notoriously known as the home of the maximum security National Bilibid Prison, where the country's most dangerous criminals were incarcerated. Prisoners used to call the prison as "Munti" after the place being erected. Nowadays, it has largely shaken-off this negative image to become one of the most progressive cities in the country.
Muntinlupa is home to some of the best commercial establishments in the metropolis and is the location of Ayala Alabang Village, one of the country's biggest residential communities, where many of the wealthy and famous live. Among the village's well-known residents include former Philippine President Fidel V. Ramos, actor Aga Muhlach and his wife, actress/host Charlene Gonzalez, the Prince of Brunei, Simone Snoeijenbos and her brother Mateo Snoeijenbos.
