Spes Altera Vitae - Hope for another life

During my trip to Europe this year, I sat on a bench right outside of an Irish pub in downtown Amsterdam. As I enjoyed my Leffe Blonde, a local favorite beer there, I looked up and saw this beautiful scene...

Turns out, this is the second oldest church in Amsterdam, St. Olof Chapel. It was built in the first half of the 15th century and is now a hotel.  

The inscription means "Hope for another life."
