I'm not really sure how to describe this place other than a more whimsical version of the Mutter Museum. We were invited to a fundraising party there and I was shocked because I had never heard of this place, and it is literally 5 minutes away from my house.
Trundle Manor is an oddity museum situated right in the middle of a quiet Swissvale neighborhood. I guess you have to call ahead for an appointment, and a suggested donation is asked for in lieu of an admission fee. What you'll find inside is a collection of unusual, cool to see things. Some artifacts of misguided ingenuity, and some just bizarre side show strangeness, all lovingly curated. This 'labor of love' feeling permeates throughout the house, and is extremely endearing.
We were there for a fundraising party, and had an amazing time. The police weren't called which seemed to indicate that the surrounding neighborhood had gotten use to having such an unusual place near them. To put it in perspective, the best thing our neighbors have done is drunkenly throw up Taco Bell on our shared entry steps twice in the last two months.
