The size of the mesh openings is really small. Maybe 2cm by 2 cm. You see faint traces in the previous pictures. Maybe I have too large a lens.
How did you get those shots? The only clear vantage point from that side has wire mesh covering it. Or was it removed?
An extemely interesting live moving shot of the site:
