Macduff
Macduff is a community in the Banff and Buchan location Aberdeenshire, Scotland. It is located on Banff Bay and also encounters the community of Banff throughout the estuary of the River Deveron. Macduff is a previous burgh and also was the last location in the United Kingdom where deep-water wood angling boats were developed. The settlement of Doune (from Scottish Gaelic dùn, "hill fort") was bought in 1733 by William Duff, that came to be the very first Earl Fife. In 1760, James Duff, the second earl, built a harbour there as well as in 1783 succeeded in increasing Doune to the standing of a burgh of barony, renaming it "Macduff" after his intended ancestor. The 2nd Earl Fife assigned his factor, William Rose, as the initial Provost of Macduff in 1783. The community commemorated its bicentenary in 1983, and the indications set up in that year still base on the main strategies to the community (most noticeably, a large indication next to the Banff Bridge on the Macduff side). Banff and Macduff are divided by the valley of the River Deveron. This unforeseeable river was lastly tamed by the seven arched bridge finished in 1799 by John Smeaton. An earlier bridge had been constructed in 1765, yet was swept away in 1768. The old ferry was revived into use, up until it was lost in a flood in 1773. Early location prehistory is manifested by the neighboring old monument at Longman Hill, a large lengthy barrow rather to the southeast of Macduff.
