Funnels

Today's pictures were taken in July this year at Herne Bay on the Kent coast.  A little further along the coast is Reculver with the imposing ruins of a Saxon monastery on the cliff which may well feature in this blog at a future date.

The pictures I have chosen for today are two different views of some unusual funnels or vents which face inland above the promenade.  It is unclear what purpose they serve and I haven't been able to find any information about them.  I think however that they make an interesting subject and I think they work equally well in colour or black and white.

I would love to see your comments about the pictures and if anybody can help me with what exactly these things are I would be very grateful.
