The Hatch Shell was built on the Esplanade in 1940 and was funded by a trust fund established by Maria Hatch as a memorial to her brother. It is used in the summer for concerts, movies, and civic events. Every year, on the Fourth of July, the Boston Pops Orchestra performs in the Hatch Shell. The concert is followed by a spectacular fireworks display. Arthur Fielder introduced outdoor concerts on the Esplanade in 1929.
