While preparing for demolition of one office building and construction of another right in the heart of London, workers just uncovered remains of the city's original Roman basilica. Built circa 80 C.E.

An office building from the 1930s in London was about to be demolished — until remnants of the city’s first Roman basilica were found in the basement.

And, he was still wearing a wedding ring. The ring was inscribed with his wedding date — Dec. 25, 1908 — and the body was identified as a German soldier from World War I, researchers said, confirmed by the discovery of his identification plate.

The 2,000-year-old basilica was “once the beating heart of Roman London,” the Museum of London Archaeology said.
