A marquee is a big tent thing - commonly used for weddings or outdoor shows because if there's one thing you can rely on English weather to do - it is rain in the summer on big events! Quite often they have removable sides, on the off chance that the sun might shine after all and actually manage to boil everyone to death inside!
