William Plankinton Mansion

[3] One of the mansion's notable ornaments was a lion's head on its external marble-faced construction.

The interior featured ornate woodwork, and the stairwell was illuminated by a stained glass window.

[5] Known as "A Merchant Prince and Princely Merchant" for his philanthropy,[6] John Plankinton owned property between Fifteenth and Sixteenth Streets on Grand Avenue and here financed three residences: one for himself (the extensively remodeled James Rogers mansion at 625 N. Fifteenth Street along with its surrounding seven acres of parkland, purchased in 1865);[7] one immediately next door, to the east, for his son William and built in 1876;[4] and one across the street for his daughter Elizabeth built in 1886-88 (at 1492 W. Wisconsin Avenue).

[13][14] After the structure was no longer used as a hospital annex, it was repurposed in 1953 as Marquette's Alumni and Athletic Office.

[15] The William Plankinton Mansion was demolished in 1969 to make way for new university facilities constructed in the 1970s.
