unrivalled

[T]his museum of the state of flux [Newmarket, Suffolk] has a climate unrivalled for the production of the British temperament. Not without a due proportion of that essential formative of character, east wind, it has at once the hottest sun, the coldest blizzards, the wettest rain, of any place of its size in 'the three kingdoms.'
