At the children's playground of the Anconella Park in South Florence one can see a small, half finished replica of Brunelleschi's cupola that was made to demonstrate one of the possible building techniques the master architect could have devised for his unique masterpiece (see also side view in the pip).

The replica shows both the herringbone bricklaying technique and the "slack rope" curvature of the various subsequent sections that make up the cupola's unusual building structure. (anyone interested can see a video illustrating this hypothesis of Brunelleschi's building technique here: brunelleschi.imss.fi.it/genscheda.asp?appl=LIR&xsl=filmato&lingua=ENG&chiave=100986 )

The openings left at ground level were later either bricked in or fenced off (or both, as can be seen in the main image), probably to keep children and pets from wandering in.

Only a rather small grid/fence this week, but HFF all the same!
I hope everyone has a pleasant weekend!
