In January 1827, the Ohio State Legislature chartered the Pennsylvania & Ohio Canal Company to build an east-west “cross cut” canal connecting north-south canals in Ohio and Pennsylvania. The route ran from the Beaver Canal in Pennsylvania to the Ohio & Erie Canal in Akron. In Ohio, the canal ran through the towns of Youngstown, Warren, Leavittsburg, Newton Falls, Ravenna, and Akron. Specifications called for the canal to be no less than 28 feet wide at the botton, no less than 40 feet wide at the waterline, and at least four feet deep. Towpaths were at least 10 feet wide and 2.5 feet above the water. (Continued on other side)

The discovery in the mid-19th century of iron-rich black band ore in this region helped revitalize Mahoning Valley’s iron industry. The land now called Mineral Ridge was primarily a farming community before the 1850s. In the 1830s, coal was discovered and mining began on a small scale. For years, it was believed that the coal seam sat on top of a layer of slate, which was considered to be of little worth. In the mid-1850s, however, John Lewis, superintendent of the Mineral Ridge Coal Mines, identified what was previously thought to be slate as valuable black band ore instead. (Continued on other side)

The land on which Coventry Township is situated was ceded in 1785 to the United States by the Delaware, Chippewa, Ottawa, and Wyandot tribes under the Treaty of Fort McIntosh. The area was a choice location for Native Americans, settlers, and fur traders due to the abundant bodies of water and proximity to the Portage Path, a land connection between the Tuscarawas and Cuyahoga rivers and Lake Erie. In 1788, Coventry Township was initially part of Washington County, the first county formed in the Ohio Territory. After Moses Warren finished a survey in 1797, a succession of county splits located Coventry Township in Jefferson County, Trumbull County, Portage County, and, finally, Summit County in 1840. The township originally encompassed Summit Lake and the lands south to the southern line of the Western Reserve (Green-New Franklin lines). Daniel Haines was the first resident to settle in Coventry Township in 1806.

Steel-frame skyscrapers and retail buildings replaced wood-frame residences as the downtown evolved into a commercial district. A small public library branch occupied the north side of the square from 1923 to 1954. The Keith-Albee Theater (later the Palace) in the northeast corner of the square from 1926 to 1964, featured vaudeville performances and movies. Streetcar tracks around the square were removed for scrap during World War II. With expansion of suburban shopping malls, downtown theaters and department stores gradually closed. In 1973-74 Central Square was converted to a pedestrian Federal Plaza by closing off traffic on Federal Street one block east and west of Market Street. Central Square reopened in 2004 with a new traffic pattern, planting beds, and street furniture. Marker for “Central Square (1798-1899)” across the street.

Designed by noted Detroit architect Albert Kahn (1869-1942), this 13-story Commercial Style building was contructed for the Mahoning National Bank in 1910 and opened in 1911. Advances in steel-frame structural systems and Kahn’s pioneering developments in fireproof reinforced concrete construction allowed buildings in America to soar to new heights. In 1925 the building’s width doubled with the addition of five bays. Rich exterior details consisting of piers joined by Renaissance-styled arches emphasize the verticality of the white terra cotta skyscraper. The windows have ornamental iron windowsill guards. The banking lobby retains much of the original lavish interior characterized by black walnut paneling, coffered plaster ceilings, and period light fixtures. The building was added to the National Register of Historic Places in 1980.

Elm Court, designed by Howard Van Doren Shaw of Illinois, was built in 1912 for Arthur Hudson Marks. The original mansion exemplifies the Italian Renaissance Revival style. Elm Court included the mansion, barn, stables, carriage house, pond, and a variety of trees, especially elms, on 33 acres. Arthur Marks was the inventive genius in chemistry and business who revolutionized the rubber industry in Akron. He was best known for inventing the alkaline-recovery vulcanization process in 1899, the cord tire, the chemical research laboratory system, and placing rubber research on a scientific basis. In World War I he served as director of chemical warfare services. Marks served as vice-president of B.F. Goodrich Company and Curtis Airplane and Engine Company and president of other rubber companies and the Aeolian Skinner Organ Company.

Born at Richford, New York, John D. Rockefeller moved to the Cleveland area with his family at age 14. He began his business career as a bookkeeper in 1855. From modest beginnings he became one of the richest men of his era by developing the world’s largest oil corporation, the Standard Oil Company, which was founded here in the Flats of Cleveland. Rockefeller moved to New York City in 1884 but maintained two homes in Cleveland, returning often with his wife Laura (1839-1915). Although he was a controversial businessman, Rockefeller donated millions of dollars to Cleveland charities and institutions, and land for Rockefeller and Forest Hills parks. John and Laura Rockefeller are interred in Lake View Cemetery.

On this site in 1882, Gustave H. Grimm (1850-1914), a German immigrant tinsmith, established the G.H. Grimm Manufacturing Company. His device, the Champion Evaporator revolutionized maple syrup production with the use of a corrugated pan which increased the efficiency of evaporating liquids such as saps. Grimm’s business became the world’s leading manufacturer of maple supplies. His contributions as an inventor, researcher, and manufacturer established him as a leader in the maple sugar industry.
