By saying city Tyre, I think you are talking about Tyre, Lebanon. It is one of the oldest continually inhabited cities in the world.
Tyre was an one of the earliest Phoenician metropolises. Today it is the fifth largest city in Lebanon and houses one of the nation's major ports.
The city has a number of ancient sites, including its Roman Hippodrome.
Part of Tyre is an archaeological site showcasing remains of the city from ancient times.
Tyre originally consisted of two distinct urban centres: Tyre itself, which was on an island just off shore, and the associated settlement of Ushu on the adjacent mainland. Alexander the Great connected the island to the mainland by constructing a causeway during his siege of the city, demolishing the old city to reuse its cut stone.
Ancient Tyre sites include:
remains of ancient columns at Al Mina
The Triumphal Arch (reconstructed)
rectangular theatre at Al Mina from the 4th century A.D.
"Ain Sur": the spring of Tyre where Jesus reportedly drank water
Roman Hippodrome in Tyre
