The two carved oak figures, known as 'Quarter Jacks', are around 400 years old or more(так как вопрос про век, можно написать что они from XVI century) and strike the hours and the quarters by tapping the rods they are holding onto the vertical tubes. Their name are Gog and Magog. A legend was attached to Gog and Magog by the time of the Roman period, that the Gates of Alexander were erected by Alexander the Great to repel the tribe.
