All Hallows by the Tower

As with any Merlin attraction, it is arguably overpriced for what it is. Brings to life the gorier elements of London's past both real life and fictional. Including the execution of Charles I after the English Civil War, the bubonic plague, Jack the Ripper, Mrs. Lovett's pie shop and Sweeney Todd's barber shop with faithful recreations of disaster, disease, and torture using live actors. Younger children may be scared.

A splendid Regency house with enormous gardens and woodlands. The gardens alone are worth the visit and are a superb example of 18th-century landscaping. On show at the house is art by masters such as Rembrandt, Turner, Reynolds and Vermeer, and the gardens have a very notable sculpture by Henry Moore. A regular program of outdoor opera takes place here every summer. Movie buffs will recognise Kenwood from Mansfield Park among other famous films. Administered by English Heritage, separately from the rest of Hampstead Heath.

Beautiful Italianate church created during the Catholic revival of the 19th century.

The Serpentine is a long, thin artificial lake within Hyde Park which contains a range of waterfowl and fish. It was first made by damming the River Westbourne but it is now fed by three boreholes. The western end of the lake is actually in Kensington Gardens, in which it is called The Long Water. Swimming and boating are popular activities on the Serpentine; see 'Do' section.

Properly St Lawrence Jewry next Guildhall, it is the official church of the Lord Mayor of London.

Constructed 1672-9 to a design by Sir Christopher Wren and regarded as one of the finest Wren churches. The 63 feet (19 m) high dome is based on Wren's original design for St Paul's Cathedral.

Free Organ recitals at 12:30PM on Fridays. Occasional art exhibitions on Christian themes and other events.

London's main zoo is in the northern reaches of Regent's Park. Takes a very conservation-driven approach these days and always has great exhibits aimed at children. Opened in 1828 for scientific study, then to the public in 1847.

Designed and built in 1619-1622 by the Neo-Classical architect Inigo Jones, The Banqueting House is now all that remains of Whitehall Palace, the sovereign's principal residence from 1530-1698 when most of it was destroyed by fire. Renowned for its architecture and paintings (by Rubens, among others), the building is also famous for being the scene of Charles I's execution in 1649 at the end of the English Civil War.
