Day five of our two-week dig saw us turn away for the time being from our primary aim of relocating trenches dug in the 1960s, to our two secondary objectives, studying elements of the palace gatehouse building that we discovered last year.

Having proved yesterday that Trench 1 does not contain any evidence of 60s trenches, and not being able to safely dig any deeper into the rubble deposit due to the risk of section collapse, we have more or less done all we can in that trench for now.

We therefore redeployed our diggers to our secondary objectives. Trench 3, at the north side of the site, is intended eventually to reveal more of a wall junction seen last year, but for now there is still a fair amount of gravel and rubble to remove before we can expect results from it.

Meanwhile Trench 2, which has had a head-start, had the last of its post-palace landscaping pebbles removed early in the morning. Late yesterday afternoon we had got a hint of the anticipated brick surface, and sure enough as the afternoon wore on the few bricks we saw yesterday did indeed acquire several friends.

We haven't revealed the whole of the brick surface yet but it does seem to have at least one edge, which seems to be running towards where the expected wall ought to be. We're probably not deep enough to see the wall yet, so there remains plenty to do to understand this feature properly.

Apart from the masses of late 19th and early 20th century rubbish in Trench 1, there hasn't been a great deal in the way of finds so far but an eagle-eyed digger did spot a rather nice probably Mesolithic tool (probably a tool for piercing leather and/or animal skins) amongst the gravel being removed from Trench 3.

Quite a morale-booster and a reminder that hunting had been going on in Enfield for several thousand years before the Tudors.
