After you have looked round Town Hall Square you are at the end of part one of the walk. We hope you have enjoyed it so far. To get back to Jewry Wall Museum: face the Town Hall. Walk to the right hand side of it into Horsefair Street. Turn first right into Berridge Street. Continue on into Grey Friars.

Turn left into St Martins (the street, not the shopping centre) and immediately right into Loseby Lane. This becomes Carts Lane. Turn left into High Street and follow to St Nicholas Circle at the top.

To continue on the walk: go on to page 9.

Town Hall Square was a Victorian horse market, and only became a park in the 20th century. If you look carefully at the stones making up the buildings you can see a loads of different types.

Carved limestone on Horsefair St.

- The highly carved stone where you came into the square (Lloyds TSB, No17 Horsefair Street) is made of Portland Oolitic Limestone. Look carefully for hard grey shell fossils in it too.

- The yellow limestone at the bottom of the Town Hall is Oolitic (meaning egg-shaped) Limestone from Ketton, known as Ketton Freestone. The Limestone is made up of tiny egg-shaped grains of calcite that were rolled back and forwards into spheres while it was forming under the sea.

Xenoliths in the fountain bowl

- The fountain base and bowl is made of Shap Granite, with distinctive large pink fedspar crystals in it. Some xenoliths can also be seen: large pieces of partially melted older rock that were engulfed by molten granite which cooled around them. They are black and look a bit like big bits of chewing gum dropped on the edge of the fountain.

- The columns around the fountain are made of Peterhead Scottish Granite. It was made about 400 million years ago.

- Plants and trees around you are: Purple Prunus cerasifera trees, cherry trees, small oak tree, plane tree and ornamental planting in the flower beds.

- There is little wildlife here (apart from the pigeons which are here all year and the starlings which form huge flocks in the autumn and winter). But there are loads of statues and carvings of real and mythical creatures in the square: look carefully around you…

If you fancy a quick extra trip 50 m down Bishop Street to the post office, look at the Post Box. Feel the smooth white Cornish Granite of the post box (and look for the tiny shiny silver bits of Mica in it).

The Bishop Street post box

Then feel the rough White Portland Oolitic Limestone on either side of the post box. The ledges about 1.5m up the walls have some good shell fossils too.
