All Hallows-by-the-Tower, London

Welcome to All Hallows by the Tower-where history isn't just in the walls… it is the walls. This venerable church dates all the way back to 675 AD, making it the oldest in the City of London. That’s right, it’s been standing since before England had shires, smartphones, or sarcasm. Miraculously, it survived the Great Fire and narrowly dodged destruction during the Blitz, though it did get a bit of a concrete facelift in the post-WWII era, now donning a rather serious neo-Gothic expression.

Step inside, and you're in for a visual treasure hunt: model ships, maritime memorials, fragments of a Flemish triptych from circa 1500, and the showstopper-an exquisitely carved limewood font cover by Grinling Gibbons (the Anglo-Dutch sculptor known for his works in Windsor Castle, the Royal Hospital Chelsea, Hampton Court Palace, St Paul's Cathedral and other London churches), casually waiting in the southwest chapel like it owns the place.

But wait-there’s more ancient wonder just outside the chapel door. Nestled nearby is a 7th-century Anglo-Saxon arch, decorated with recycled Roman tiles-yes, the Romans were here first. This humble arch is the oldest surviving piece of church architecture in the entire city, and it’s just sitting there like it hasn’t aged a day.

Head downstairs to the Crypt Museum, and you’ll find bits of Roman pavement in all their tessellated glory, plus pre-Reformation brasses that have seen more candles than a cathedral gift shop. Entry is free. Knowledge is priceless.

And because location is everything, All Hallows found itself next door to the Tower of London-so naturally, it made a few royal connections. Edward IV turned one chapel into a royal chantry, and the church became the temporary resting place for unfortunate Tower victims. Think of it as the VIP lounge for history’s more tragic characters.

Ultimately, it'd be fair to say that, apart from being a church, All Hallows is a true stone-and-mortar time machine with surprisingly good lighting.
