They Pelennor Fields lay just outside the city of Minas Tirith, on the west bank of the river Anduin. The land ran down toward the river in slopes and terraces. The City of Minas Tirith was located on the southwestern corner of the fields, at the foot of Mount Mindolluin.
A road ran northeast across the Pelennor Fields to the Causeway Forts on the river bank; a distance of 12 miles. The North-way led from the City through the fields to the Forannest, or north-gate, before turning westward to become the Great West Road to Rohan. The South Road came from the southern provinces of Gondor and passed through the Pelennor Fields on the way to Minas Tirith. A number of other paths also criss-crossed the fields.
The Pelennor Fields were home to farmers and herdsmen who had barns, pens, livestock, granaries, and kilns for drying hops and malt which were located on the Pelennor. The fields were fertile farmland, with tilled fields, orchards, and small brooks flowing down to the Anduin.
After Minas Ithil had fallen and been renamed Minas Morgul, the Fields were walled by the great wall of Rammas Echor by Ecthelion II in T.A. 2954, to prevent an invasion and presumably the Fields took their name because of this enclosure
During the War of the Ring, the people and livestock evacuated the lands seeing the coming invasion of the forces of Sauron. Indeed Orcs and evil Men overran the Rammas Echor and besieged the city. Homes and trees were burned and trenches were carved through the fields and filled with fire. The Pelennor Fields were the location of the ensuing Battle of the Pelennor Fields, when Théoden, King of Rohan and the Lord of the Nazgûl and his Fell beast were slain.
 After the Battle
After the battle, the grass began to grow back on the fields, Snowmane's Howe, where Théoden's horse was buried, grew especially green. The location at which the Witch-king and his steed had been killed was stained black and no grass grew from the scorched earth.
The name Pelennor translates to "fenced, encircled land" in Sindarin. Christopher Tolkien has noted that the first element derives from the Elvish root/element pel- ("go round, encircle"); the other elements appear to be end (from enedh "middle")' + (n-)dor ("land, dwelling"). The field was called by several other names as well, such as Fields of Pelennor, the Pelennor, and the townlands.
