The figure in bars 17-24 is supposed to evoke the central “White Tower” part of the Tower of London with a small tower at each corner all surrounded by an outer wall. The two handed turns represent the towers while the intervening inner and outer chases are the walls. Three of the four towers are square - only the one at the north-east corner (between 1st and 2nd places) is round. So those concerned with architectural exactitude can make their turns at the other corners as square as possible, for example making angles at the half bar points.  Those keen on symbolism may see sceptres and orbs or loops of a crown in bars 1-8 and 9-12. Bars 25-32 were inspired by the end of <<ddd:Vana Tallinn>> by <<ddp:Garbuzov, Vladimir>>.
