menagerie とは動物園。
2:59 the Tower was a Royal residence but it was never that popular as a palace. it has also served as the Royal Mint, an armory, storehouse, cannon factory, and was even a menagerie with lions and an elephant and a polar bear kept there until the mid-1800 when the London Zoo was created. ロンドン塔は王室の住処としては有名ではなかった。ここは造幣局、武器貯蔵庫、倉庫、大砲製造工場、そしてロンドン動物園ができるまでは動物園として色々な動物を飼っていた。
