What is this floor covering called?

Parquet is a geometric mosaic of wood pieces used for decorative effect in flooring.

Parquet patterns are often entirely geometrical and angular—squares, triangles, lozenges—but may contain curves. The most popular parquet flooring pattern is herringbone. The word derives from the Old French "parchet" , literally meaning "a small enclosed space".

Parquet floors are usually long lasting if maintained correctly. Parquet floors are often found in bedrooms and hallways. They are considered better than regular floor tiles since they feel warmer underfoot.

Large diagonal squares known as "parquet de Versailles" were introduced in 1684 as "parquet de menuiserie" ("woodwork parquet") to replace the marble flooring that required constant washing, which tended to rot the joists beneath the floors.

One of the most famous parquet floors is the one used by the Boston Celtics (American professional basketball team). The original floor, which was installed at the Celtics' original home of Boston Arena in 1946, was moved intact to Boston Garden in 1952 and used there until the team moved to what was then known as FleetCenter in 1995, now known as TD Garden. The floor remained intact and in use until it was cut up and sold as souvenirs in 1999, after the 1998 demolition of Boston Garden.
