The FIBT World Championships 1957 took place in St. Moritz, Switzerland for the record eighth time. The Swiss city had hosted the event previously in 1931 (Four-man), 1935 (Four-man), 1937 (Four-man), 1938 (Two-man), 1939 (Two-man), 1947, and 1955. It also marked the first time the unified championships took place in the same location in consecutive championships.
This is Spain's only medal at the FIBT World Championships as of 2016. Portago would die later that year in the Mille Miglia competition in Italy.
