786 Castles with a swimming pool for sale

Every property on this page already has a swimming pool, which matters more than it might seem in the context of a historic building. Where a castle or its grounds are protected, adding a pool requires consent and is usually only approved away from the principal façade, out of key sightlines, and without visible modern plant — a hurdle that these properties have already cleared, which is exactly what this filter is for.

Not all of the pools are heated, and listing copy does not always say so either way. It is worth asking specifically: at these latitudes an unheated outdoor pool has a genuinely short usable season, and retrofitting heating to a pool positioned some distance from the house — as estate pools often are — can be a significant piece of civil and mechanical work rather than a simple addition.

Running costs scale with size rather than with the size of the house around it. Pools built as estate features are frequently much larger than a domestic pool, and heating and water treatment costs rise with volume, not with prestige. Ask the current owner for actual annual figures rather than estimating from a typical domestic pool — the two are rarely comparable.
