John Keats was buried in Rome’s Protestant Cemetery. His tombstone doesn’t mention him by name but says this is the grave of the “Young English Poet”. Buried next to him is the artist Joseph Severn, who looked after Keats during his final illness. Servern lived to be 85 years old, spending quite a bit of his life in Rome. The small tombstone in between the larger ones is for Severn’s son Arthur who died as an infant.
The Protestant Cemetery is next to the Pyramid of Caius Cestius which was built in 30 BC as a tomb and was later incorporated into the Aurelian Walls. The cemetery is open to visitors every day (closed Sunday afternoon) and can be reached by Metro line B to Pyramide station.
