National League Park, commonly referred to as the Baker Bowl after 1923, was a baseball stadium home to the Philadelphia Phillies from 1887 until 1938, and the first home field of the Philadelphia Eagles from 1933 to 1935. It opened in 1887 with a capacity of 12,500. It burned down in 1894 and was rebuilt in 1895 as the first ballpark constructed primarily of steel and brick and with a cantilevered upper deck.
The ballpark's first base line ran parallel to Huntingdon Street; right field to center field parallel to North Broad Street; center field to left field parallel to Lehigh Avenue; and the third base line parallel to 15th Street. The stadium was demolished in 1950.
