Every city has a neighborhood that housed its earliest founders and their successors, an enclave of local power and financial success. For Rochester, Minnesota, this neighborhood is personified by a ten-block stretch of tree-shaded street originally platted in 1855 as West College Street, now designated as 4th Street Southwest. In the span of 150 years, two and sometimes three generations of remarkable buildings have come and gone in this neighborhood. Under the direction of movers and shakers like George Head and Dr. William J. Mayo, the street helped shape the city's architectural legacy and define its purpose. Join architectural historian Ken Allsen on a stroll down this storied street.
