The complete title of the poem is "Lines composed a few miles above Tintern Abbey, on revisiting the banks of the Wye during a tour. July 13 1798."
The river Wye is the fifth longest river in the UK and part of it forms the border between England and Wales. It flows through regions famous for their natural scenic beauty. The spectacular ruins of the medieval Tintern Abbey are located on the banks of the river Wye at Monmouthshire.
Wordsworth begins the poem by telling us that he is revisiting this scenic and tranquil spot after five years. He tells us how the memory of "these beauteous forms" have had a benign influence on him even during their absence when he was alone or in crowded towns and cities.
The entire poem is a monologue about the benign and life sustaining power of childhood memories of a beautiful scenic spot in the wild open Nature. The poem reveals to us how these memories serve to link his past, present and future: "While here I stand, not only with the sense/Of present pleasure, but with pleasing thoughts/That in this moment there is life and food /For future years."
