塞沃尔是位于英格兰北柴郡沃灵顿郊区的一个城市。

Thelwall is a suburban village in Warrington, Cheshire, England, located close to the Lymm junction of the M6. It is a popular misconception that Thelwall is the 'smallest city in England' (although Thelwall is not in fact a city, nor if it were would it be the smallest in England as the City of London, which truly is the smallest city in England, is marginally smaller).
