The ornate Metropolitan Drinking Fountain, originally erected in 1866 outside the Church of St Lawrence Jewry, was a generous gift to London from the Metropolitan Drinking Fountain and Cattle Trough Association. Designed by architect John Robinson with bronze sculpture work by Joseph Durham, this Victorian fountain was carefully dismantled into approximately 150 pieces during the Guildhall redevelopment in the 1970s and placed in storage.

Day's Lock is a lock on the River Thames near Dorchester-on-Thames, Oxfordshire, England on the Dorchester side of the river. The pound lock was built in 1789 by the Thames Navigation Commissioner. The lock is across the river from the small village of Little Wittenham and is overlooked from the south by the hills of Wittenham Clumps, with a particularly good view from Round Hill. The weir runs straight across the river from the other side of the lock island. Day's Lock is the main gauging station for the measurement of the water flow in the River Thames.

Little Wittenham Wood has been designated as both a Site of Special Scientific Interest (SSSI) and a Special Area of Conservation (SAC), reflecting its international importance for wildlife. The nature reserve is particularly important for the endangered species, the Great Crested Newt. This shy amphibian uses the many ponds within the nature reserve to breed, but it spends the majority of time in the surrounding woodland. Tucking itself quietly away in safe and secure hidden spots, you have to search carefully to find them. Much easier to spot are the dragonflies and damselflies which hover around the ponds. If you wander down to the bird hide, at the river’s edge, you might be lucky enough to catch a glimpse of Kingfishers or Otters.

In 2012, Lisa Kuppler (Frankfurter Allgemeine Sonntagszeitung) paid tribute to the writer J.R.R. TOLKIEN (1892 to 1973), who invented a fictional world called Middle Earth inhabited by 'hobbits', with the words: "It is this complex creation of an entire world that makes 'The Lord of the Rings' the original text of the fantasy genre." Two decades earlier - on the occasion of his 100th birthday - a bench and two trees were dedicated to him here, in Oxford's university park. Tolkien's most popular work to date includes the volumes: "The Fellowship of the Ring" (Volume 1); "The Two Towers" (Volume 2); "The Return of the King" (Volume 3). Many people may not have read his books, but they know the film version of this great myth.
