With the generous support of its members, the BWS organises an annual maintenance of Wittgenstein's ledgerstone. Objects left by visitors are stored with the stonemason in the chapel workshop. Some earlier history relating to the BWS maintenance project can be found here.
The BWS also organises the maintenance of the nearby Anscombe and Geach stone. We thank the Collegium Institute at the University of Pennsylvania for their generous support.
The BWS wishes to express its thanks to Gregg Kaniak for his invaluable assistance.
