Mountain building involves either volcanism (which exposes rock to immense heat from magma and lava) or block faulting, or folding (which results from enormous pressures between colliding tectonic plates) or a combination of those things. Heat and pressure are what turns material into metamorphic rock.
Furthermore, mountain formation sometimes raises metamorphic rocks that have formed deep in the crust to higher locations, where they can be exposed at the surface when the rocks above them erode away. Thus some mountain formations also contain metamorphic rocks that were brought to the surface by mountain-building even though they weren't formed by it.

Large scale folding of rocks during the process of mountain building is characteristic of regional metamorphic rock
Most coal is sedimentary, but anthracite is metamorphosed bituminous coal, a result of mountain building pressures on sedimentary coal.

Metamorphic rock such as marble make good building material because of it's strength and durability. It is highly desirable in that it takes a high polish.

Most metamorphic rocks are very hard. They are often impermeable. These factors make them useful for building materials which last well.
The Old Man of the Mountain was a series of rocky ledges composed of granite, a type of igneous rock. Granite is a common rock type found in mountainous regions due to its durability and resistance to weathering.

The Himalayas are mostly metamorphic and sedimentary rock.
