Springfield is located on the Connecticut River about 90 miles (140 km) southwest of Boston and about 30 miles (48 km) north of Hartford. It is a center of finance, industry, commerce, education, and culture for the western part of the state. European settlement began in 1636, when English colonists led by William Pynchon bought land here from the Agawam Indians. Industrial growth was spurred by the armory in the late 1790s and by the coming of the railroad in 1839. By the 1850s, Springfield had become a major railroad center and had been chartered as a city in 1852. Construction of 1200 Main Street in 1907-08 caused an outcry which led to a law limiting commercial building height to 125 feet – the height of the steeple of the Old First Church, now the First Church of Christ Congregational. As a consequence, Springfield did not develop a skyline of tall commercial buildings in the pre-WWII styles of neo-classicism or art deco. The height limit was not breached until 1970 with construction of the Tower Square. Several major downtown projects followed in the 1970s and 1980s, creating an impressive modern skyline accented by the Campanile tower of 1913.
