The Pabst Mansion is an architectural gem in Milwaukee. The famous house on Wisconsin Avenue was the official residence of the Archbishop of Milwaukee for 67 years in the post-Pabst family phase of the mansion's history. Below is a view of the private chapel used by the archbishops. Not bad, eh? Now the Pabst Mansion is maintained by a historical society (the chapel is now a gift shop). It had been slated for demolition to make room for a parking lot (no, really) but was saved at the eleventh hour in the late seventies.
Here's an interesting story about the mansion's storied past, appearing in the Milwaukee Journal Sentinel.
