Andromeda Rock, Ancient coastal landmark in Jaffa, Israel.

Andromeda Rock is a jagged rock cluster rising from the Mediterranean in front of Jaffa's old beach. It has a taller rounded tan-brown mass on the left and a lower connected shelf to its right, with smaller dark wet rocks around the base. Pliny the Elder and Flavius Josephus reported seeing marks of Andromeda's chains on the rock.

From the 4th century BCE, Pseudo-Scylax placed Andromeda's sacrifice at Joppe, today's Jaffa. Pliny the Elder and Flavius Josephus reported a rock there bearing marks of her chains, and locals displayed bones they took to be the sea monster Ketos.

The name comes from the Greek myth of Andromeda, chained to a rock at Joppe and rescued by Perseus. Pliny the Elder and Flavius Josephus wrote that marks of her chains were shown on the rock, and Jaffa's residents displayed bones they took for the sea monster Ketos and honoured a fish goddess called Ceto.

The best times to visit are early morning or late afternoon when the light is most pleasant. You can view the formation from the coastal promenade where several viewpoints are available.

Pliny the Elder and Flavius Josephus wrote that marks from Andromeda's chains could still be seen on the rock, and Jaffa's residents displayed the bones of a large sea creature they took for the Ketos. Pausanias adds a spring nearby whose red-tinted water was said to be where Perseus washed off the monster's blood.
