Another lunchtime escapade

Today's lunchtime walk led me to Postman's Park. I took a work colleague to see G.F. Watt's Memorial to Heroic Self Sacrifice. It was built in 1900 and contains 54 memorial tablets dedicated to women, men and children who died trying to save the lives of others.
Next to Postman's Park is St Botolph-without-Aldersgate. The church contains the only surviving painting on a glass window in the City of London.
The East Window, painted by James Pearson in 1788, depicts Christ's agony in the Garden of Gethsemane before the crucifixion.
