Probably to protect them from people and horses.
We noticed this first last night, though work has been going on in the park for some time.
The sunken beds with bushes and shrubs have been paved over. The huge trees rise from amidst paving stones.
This morning I went to investigate the trees in daylight, before the caleche drivers were much interested in touting for trade.
They were chatting with their friends and I noticed anew how bright and colorful everything is.
I remember Ghislan being surprised that we don't commonly take caleche rides in New York.
In fact, I never have been in a horse carriage in New York.
Even men on their way to work manage to avoid drab uniformity.
