"And far beneath, in lustre wan, old melros rose, and fair tweed ran." Melrose. The magnificent ruins of Melrose Abbey are situated amid the beautiful scenery of the valley of the Tweed. The original abbey was founded by David I, in 1136 and during the succeeding 400 years was several times destroyed and rebuilt. The heart of Robert Bruce is interred below the spot where stood the high altar, and many Scottish heroes and dignitaries are buried within its precincts.
