The Metropolitan Museum of Manila is one of the city's more serious art stops, with exhibitions that move between Philippine art, design, contemporary work, and international material. Its scale is manageable, which can be a relief in a city where travel between sights often takes longer than expected.
It fits naturally into a Malate and Roxas Boulevard day, especially if you are already visiting nearby cultural institutions or walking the bayfront. Check current exhibitions before going; the museum's strength depends heavily on what is showing.
