This is another city in the southernmost of Metro Manila, situated on the other road to the South, the South Luzon Expressway, which runs to the East of the road skirting the Laguna de Bay. Muntinlupa is renowned for its fruit, which is sold by the roadside. During the last decade, the city has undergone rapid development particularly in its Alabang district. The once pasture land in 1980s trasformed into a super city that houses new residential, business, industrial and commercial establishments. The largest malls in the country – Alabang Town Center, Festival Mall and Manuela Metropolis, are situated in the city. The national penitentiary is also situated here.
