The Spillings Hoard is the world's largest Viking silver treasure, found on Friday 16 July 1999 in a field at the Spilling farm northwest of Slite, on northern Gotland, Sweden. The silver hoard consisted of two parts with a total weight of 67 kg (148 lb) before conservation and consisted of, among other things, 14,295 coins most of which were Islamic from other countries. A third deposition containing over 20 kg (44 lb) of bronze scrap-metal was also found. The three caches had been hidden under the floorboards of a Viking outhouse sometime during the 9th century.

Gotland, also historically spelled Gottland or Gothland, is Sweden's largest island. It is also a province/county, municipality, and diocese. The province includes the islands of Fårö and Gotska Sandön to the north, as well as the Karlsö Islands to the west. The population is 61,001, of which about 23,600 live in Visby, the main town. Outside Visby, there are minor settlements and a mainly rural population. The island of Gotland and the other areas of the province of Gotland make up less than one percent of Sweden's total land area. The county formed by the archipelago is the second smallest by area and is the least populated in Sweden. In spite of the small size due to its narrow width, the driving distance between the furthermost points of the populated islands is about 170 kilometres (110 mi).
