"Once out of the Garden City and over the A1(M) you are in some attractive Hertfordshire countryside, including the landscaped parkland of Brocket Hall and Lamer House. In the afternoon you reach the picturesque village of Ayot St Lawrence, which has two unusual churches – one reminiscent of a Greek temple, the other an ivied Gothic ruin – and if you wish you can visit the home of George Bernard Shaw, Shaw's Corner, now owned by the National Trust. (Open to the public from 1300, garden 1200)"
