Part of Pennsylvania's wealthy Main Line corridor that popped up along the rail line of the same name, Lower Merion got its start when railroad executives built massive summer homes here. Today, it's an elite suburb of Philadelphia and dotted with colleges, including women's liberal arts school Bryn Mawr, which is also one of the township's largest employers.
Residents bring lawn chairs and blankets to twilight concerts at the Bryn Mawr Gazebo all summer long and enjoy their pick of sledding hills in the winter months. The area's 682 acres of parkland and top-rated schools in the state form a well-rounded nest for well-heeled Pennsylvanians.
