I'm sure it will have been fully checked and there are means to chemically analyse for carbonation if steel is suspected to be present but it would be nice to know it had been.


Perhaps someone could ask English Heritage's Ask the Experts ;-)

The most recent photo I've seen of the lintel shows what appears to be a vertical join to the right of the 1968 plaque. That would imply that the lintel is reinforced. Bottom edge of plaque shows some spalling. Orange hue to the concrete, though that might be discoloration from the earth covering (if it was covered with earth and not chalk). Green patina on the Superman door suggests copper.

None of this belongs in Silbury, any more than a commemorative plaque nailed to a Stonehenge trilithon would.
