Tyre around 450 BC at the end of the Greco-Persian Wars (499–449 BC), and wrote in his Histories that according to the priests there, the city was founded around 2750 BC, as a walled place upon the mainland, now known as Paleotyre (Old Tyre). Archaeological evidence has corroborated this timing. Coast Nature Reserve Tyre enjoys a reputation of having some of the cleanest beaches and waters of Lebanon. However, a UN HABITAT profile found that "seawater is also polluted due to waste water discharge especially in the port area". There is still also considerable pollution by solid waste. The Tyre Coast Nature Reserve (TCNR) was decreed in 1998 by the Ministry of Public Works. It is long and covers over . The TCNR is within the best preserved stretch of sandy coastline in southern Lebanon and divided into two section zones: a 1.8-km sand lined beach, 1.8 km long and 500 meters wide-ranging from the Tyre Rest House in the north to the Rashidieh Refugee Camp in the South, and a stretch of 2 km with agriculture lands of small family farms and the springs of Ras El Ain with three constantly flowing artesian wells, ranging from Rashidieh to the village of Chaetiyeh in the South. The former is divided into two zones: one for tourism that features a public beach of some 900 m and restaurant tents during the summer season hosting up to 20,000 visitors on a busy day, and another 900 m of conservation zone as a sanctuary for sea turtles and migrating birds. Due to its diverse flora and fauna, the reserve was designated a Ramsar Site in 1999 according to the international treaty for the conservation and sustainable use of Wetlands, since it is considered "the last bio-geographic ecosystem in Lebanon". It is an important nesting site for migratory birds, the endangered Loggerhead and green sea turtle, the Arabian spiny mouse and many other creatures (including wall lizards, common pipistrelle, and European badger). Also, there are frequent sighting of dolphins in the waters off Tyre. Altogether, the TCNR includes 275 species distributed over 50 families. In addition, the reserve is home to seven regionally and nationally threatened species, 4 endemic and 10 rare species, whilst 59 species are restricted to the Eastern Mediterranean area. It is also worthy to indicate that, several bio-indicator species as well as 25 medicinal species were recognized. TCNR encloses flora
