What is the name of the city of the Laestrygonians?

The city of the Laestrygonians is called Telepylus.

In Book 10 of the Odyssey, Odysseus and his fleet reach Telepylus, the fortified settlement of the giant Laestrygonians. The harbor is enclosed by steep cliffs, with a narrow entrance, so the visiting crews bring their ships safely inside. Odysseus alone keeps his vessel outside the harbor, securing it to a rock.

That decision saves his ship. The Laestrygonians attack by hurling enormous stones and spearing sailors like fish. Every ship inside the harbor is destroyed, while Odysseus cuts his own ship’s cable and escapes. The episode leaves him with only one ship and a drastically reduced crew.

The name is also spelled Telepylos, and the meaning is commonly explained as “far-off gate” or “great-gated.” The question’s stored form, Telepylus, is a standard English variant. Lamos is the main possible source of confusion: Homer describes Telepylus as the citadel or stronghold of Lamos, which may refer to a founder, ruler, island, or place-name in different interpretations. The city name itself remains Telepylus.
