"Another Lisbon survivor, the baroque Church of São Domingos not only stood its ground during the 1755 earthquake, but also endured a bloody anti-Semitic massacre in 1506 and a devastating fire in 1959. The gorgeous cathedral, which dates back to 1241, is not without its scars, however—its interior is rife with gouged pillars, decrepit walls, and battered sculptures, all of which look even more ethereal when lit by a sea of candles. It feels like a house of worship in constant mourning, and will leave you in a very different mood than most other churches. If you can stomach it, stop outside at the Star of David memorial, which honors thehundreds of Jews that were killed in the 1506 Easter Slaughter."
