This “island church”, located in the middle of the Strand just outside the Royal Courts of Justice, is believed to have been the eventual burial site of King Harold I “Harefoot” who died in 1040.

The son of King Cnut, Harold’s rule was brief. Following the death of his father, he initially ruled as regent on behalf of his father’s heir and younger half-brother Harthacnut (Harthacnut was in Denmark and threats to the kingdom meant he couldn’t leave).
While Harold had apparently sought to be crowned king from the start of his rule (without success thanks to the opposition of Aethelnoth, the Archbishop of Canterbury), it was only in 1037 that, with the support of Leofric, the Earl of Mercia, and other nobles, he was crowned king.
But Harold (who was known by the name Harefoot apparently due to his speed and skill at hunting) died in 1040 and his brother subsequently returned from Denmark to claim the throne peacefully.
The story goes that King Harold had originally been buried in Westminster but that Harthacnut (clearly not a fan) had his body exhumed and flung into marshlands by the River Thames. The body was said to have been found by a fisherman who then had him buried at the church.
It had been established in the ninth century to serve the Danish community which was established after King Alfred the Great had granted them land.
Of course, the current church was not one King Harold would have recognised, having last been completely rebuilt in the 1680s to the designs of Sir Christopher Wren (and then having had its interior completely restored after it was gutted when bombed during World War II).
St Clement Danes, also known as one of the contenders for the church mentioned in the song Oranges and Lemons, is now the central church of the Royal Air Force. It’s one of two “island churches” in the Strand, the other being St Mary le Strand.
