The International of 1862, or Great London Exposition, was a world's fair. It was held from 1 May to 1 November 1862, beside the gardens of the Royal Horticultural Society, South Kensington, London, England, on a site that now houses museums including the Natural History Museum and the Science Museum (London).

The exposition was sponsored by the Royal Society of Arts, Manufactures and Trade, and featured over 28,000 exhibitors from 36 countries, representing a wide range of industry, technology, and the arts. All told, it attracted about 6.1 million visitors. Receipts (£459,632) were slightly above cost (£458,842), leaving a total profit of £790.

It was housed on 23 acres (9 hectares) of land, within a special building designed by Captain Francis Fowke (1823-1865) and built by Charles and Thomas Lucas and Sir John Kelk at a cost of £300,000 covered by profits from the Great Exhibition of 1851. The building consisted of a main structure with two adjoining wings set at right gles for machinery and agricultural equipment; the wings were demolished after the Exhibition. Its main facade along Cromwell Road was 1152 feet (351 m) in length, and ornamented by two crystal domes, each of which was 260 feet (79 m) high. Although they were then the two largest domes in the world, their effect was to some unimpressive, and they were derided as "colossal soup bowls" and "a national disgrace." The building as a whole was termed "a wretched shed" by The Art Journal. Parliament declined the Government's wish to purchase the building and the materials were sold and used for the construction of Alexandra Palace.

Exhibitions included such large pieces of machinery as parts of Charles Babbage's analytical engine, cotton mills, and maritime engines by the firm of Henry Maudslay, as well as a range of smaller goods including fabrics, rugs, sculptures, furniture, plates, silver and glass wares, and wallpaper. The exposition also introduced the use of caoutchouc for rubber production and the Bessemer process for steel manufacture.

When all was said and done, however, the exhibition was generally judged a failure as compared to the Great Industrial Exhibition of 1851.

The 1862 building was a totally new building in South Kensington: http://www.british-history.ac.uk/report.aspx?compid=47522
