Here are some ideas for special interest tours of London that I can guide. Look also at the walking tours page for tours themed along similar lines, but in very focused geographical areas. If you want to do something that isn't listed here, contact me, and if I can't do it myself, I can probably recommend someone who can.

Architecture
1. London's newest buildings: a look at the work of some of our leading architects in central London, Docklands & the Jubilee Line
2. The work of individual architects, eg:
Sir Christopher Wren - Wren's City Churches, Wren's Royal Palaces.
Sir John Soane - the Sir John Soane Museum, Pitshanger Manor, & other examples of his work, eg. the Bank of England.
3. The architecture of a particular period or type, eg:
Medieval churches
Historic Houses
The great Victorian architects & engineers, their railway stations, bridges & public buildings.

Gardens
My interest in gardens is from the point of view of their history & design. As well as a number of small, private gardens that will open by special arrangement, London has some interesting historic gardens, eg Chiswick House, Ham House, Syon House, Hampton Court Palace. For the botanists, there's the Chelsea Physic Garden and Kew Gardens. Many garden tours are timed to coincide with the annual shows at Chelsea & Hampton Court.

History
1. Historical periods & themes eg:
The Romans - the City Wall, the Amphitheatre, the Mithraeum, bath house remains, the Museum of London, the British Museum.
Kings, Queens & Government.
2. Religious Heritage, eg:
The Wesleys in London
The Reformation

Writers & the Theatre
1. Individual writers, eg:
William Shakespeare - A lot of Shakespeare's London has disappeared, but it is still possible to see the streets where he lived, some of the places where his plays were performed, the church where his brother was buried, and of course the new Globe Theatre with its museum, and his work in the British Library.
Dorothy Dunnett - the Lymond Chronicles: Lymond & Philippa in London

Anniversaries
1. The 1000th anniversary of the birth of King Edward the Confessor was celebrated in October 2005. His London has largely disappeared, but it is still possible to recall him at Westminster Abbey, St Paul's Cathedral, London Bridge, the Palace of Westminster, and in art works of his time.
2. 2006 is the 200th anniversary of the birth of Isambard Kingdom Brunel, the great Victorian engineer. London is lucky to have examples of his work, and also those of his father Marc & son Henry Marc.
3. 2006 is the 150th anniversary of the birth of George Bernard Shaw. Although a Dubliner, Shaw spent much of his adult life in London, where he took part in local politics, and was a founding member of the Fabian Society.
