Broken once-palatial gates

The ancient iron gates that guard the perimeter of Patshull Hall on the extremes of the estate have, a lot of them anyway, fallen pretty much into disrepair, and are leaning over, crumbling, or overgrown.

However, underneath the decay, one can see the splendour that once was there.
This photo shows the top of one gate pillar (next to the estate church), with worn heraldic signs and what could be the broken sculpture of a small bird, but actually could be anything.
I suppose the decoration must be something to do with the Legge family, who owned the estate as the Earls of Dartmouth in the nineteenth century.
