Laigh Milton Viaduct is a railway viaduct near Laigh Milton mill to the west of Gatehead in East Ayrshire, Scotland, about five miles (eight kilometres) west of Kilmarnock. It is probably the world's earliest surviving railway viaduct on a public railway, and the earliest known survivor of a type of multi-span railway structure subsequently adopted universally.
The viaduct was restored in 1995–1996 and is a Category A listed structure since 1982. It bridges the River Irvine which forms the boundary between East Ayrshire and South Ayrshire.
It was built for the Kilmarnock and Troon Railway, opened in 1812; the line was a horse drawn plateway (although locomotive traction was tried later). The first viaduct was closed in 1846 when the railway line was realigned to ease the sharp curve for locomotive operation, and a wooden bridge was built a little to the south to carry the realigned route. This was in turn replaced by a third structure further south again, which carries trains at the present day.

Le Lude is the most northerly château of the Loire Valley and one of the last important historic castles in France, still inhabited by the same family for the last 260 years. The château is testimony to four centuries of French architecture, as a stronghold transformed into an elegant house during the Renaissance and the 18th century. The monument is located in the valley of Le Loir. Its gardens have evolved throughout the centuries.
