My daughter, Carolina, and I took an explore here when she was visiting a few weeks ago. We tiptoed through several of the 8 floors of crypts. It's not as spooky inside as I'd expected and is generally well lit, though chilly. It has many floor to ceiling windows looking out over Oaks Bottom, lots of statuary with fountains, faux skylights, some stained glass. Here's some info I found on Yelp* :
The Portland Memorial is a funeral home and mausoleum. And the
mausoleum is huge: 3.5 acres. It houses more than 58,000 bodies and has room for another 120,000.
The mausoleum was started in 1901, melds a variety of
architectural styles (Victorian, art deco, etc.) and contains floor after floor
and wing after wing of strange, spiraling architecture, Portland history (many
pioneer families are entombed here). It's a fine place to marvel at history, at
the variety of ways in which people choose to memorialize their lost loved ones, or just to chill-- literally. (posted by Christen M, Portland, OR)
