'Floodtide' (Tidal Sonification) by John Eacott and Andrew Baldwin

The 'Floodtide' (Tidal Sonification) listening post, at Trinity Buoy Wharf, makes music that is determined by the tide of the River Thames, which is then played through the mechanical organ.

A sensor, submerged from the pier, reads tidal flow data, such as height and speed, which is then converted into musical parameters like pitch, duration, and volume using a computer algorithm. 

The algorithm translates the tidal data into musical scores, which can be displayed on screens or mobile devices, so that musicians can incorporate the music into their own works.

'Floodtide' performances have taken place in various locations, including the Royal Observatory, Greenwich and the Southbank Centre, with each performance reflecting the unique characteristics of the location's tides. 

The machine was built by Andrew Baldwin, while the music by John Eacott.

KGB Lamppost, Mayfair

In Mayfair, at the corner of South Audley Street and Audley Square, outside the University Women’s Club, stands this Victorian lamppost.

It is exactly the same as the rest of the lampposts, along this street, but this one has a tale to tell.

From the 1950s the USSR had KGB agents placed in England, with orders to gather information and pass it back to their superiors. Some agents worked at the Soviet Embassy, which was under close watch by MI5, but 'illegal' agents had to find another way to pass their information on. 

So, this lamppost was used as a 'dead letter drop'. Agents would conceal their documents, or messages, behind the door of the lamppost, before leaving a chalk mark at its base, notifying their superiors that a message was contained within. Their superiors could also leave instructions or messages for the agents to collect.

In 1985, British intelligence managed to extract their secret agent, Colonel Oleg Gordievsky, from Moscow, without the ever watchful KGB even noticing. It was Colonel Gordievsky who alerted British Intelligence to the lamppost, which was soon put under surveillance. Word must have spread fairly quickly, through the KGB, because by 1986 it was no longer in use.

Interestingly, or ironically, EON Productions had their offices at No. 3, next door to the University Women's Club, from 1961. EON Productions was created by Albert 'Cubby' Broccoli and Harry Saltzman who auditioned Sean Connery for the first James Bond film, 'Dr No', in their office overlooking the KGB lamppost.

I was quite surprised, on my visit, to see that the door of the lamppost wasn't locked, but ajar.

Cuneiform Tablet: The oldest object in the City of London

London is home to many ancient and wondrous items, many of which are kept in museums and galleries. But, there are also ancient and historic objects simply dotted around London's many streets and thoroughfares.

The oldest of these objects would have to be the Needle of Thutmose III, which stands on Victoria Embankment. This obelisk dates from around 1450 BC.

Then there are the Roman remains, such as the amphitheatre, the old city walls and bastions, mosaic and the like. These were all created from 45 AD onwards.

However, this curious brown block, on display in St Vedast-alias-Foster Garden, is, I am sure, one of the oldest objects, as it dates from between 858 and 834 BC. 

So, how did it end up in a church courtyard in London?

East India Docks, Blackwall

The East India Docks were constructed between 1803-1806 and were the third set of wet docks built on the River Thames, in the early 19th century. By the end of the 18th century East Indiamen ships had been sailing from Blackwall for almost 200 years.

The East India Company, founded in 1600, shipped valuable goods from the East to the River Thames. It was a rich, powerful and well organised body using the largest two ships that frequented the Port of London. The valuable cargoes were moved by barge to the city, then carried to the company's spacious warehouses on Billiter Street and Cutler Street.

In January 1804 the lock was widened to 48 ft across to allow the largest East Indiamen, of up to 1,500 tonnes, to enter the docks.

The Export Dock

In September 1804 Hugh McIntosh used a horse operated bucket dredger to excavate 8,000 tonnes of mud from the former ship repair yard, Brunswick Dock, to give a uniform depth of 22 ft. The south wall was built in brick, but the original timber walls of the Brunswick Dock were retained on the other three sides.

The Export Dock was also home to the emigrant's ships. In the 19th century companies including Green's, Wigram's and Dunbar's all used the docks as their embarkation point. By 1905 the Export Dock was principally used by sailing ships and steamers.

After suffering from bomb damage, during World War II, the Export Dock was sold in 1946 and filled in to make way for Brunswick Wharf Power Station. The power station was closed down in the 1980s and demolished. Now the site is home to Virginia Quay.

The Import Dock

The most important element of the East India Docks was the Import Dock. Covering almost 60 acres it provided room to unload the precious goods from the East Indiamen returning from their voyages.

Excavations began in 1803 using pumps, buckets, rods, pipes, and valves impounding 18 acres of water.

The work included a labour force of up to 400 men and 100 horses. Dredging 625,000 cubic yards of earth. Making nine million bricks from the excavated topsoil to form the dock walls and using 50 tonnes of old iron hoops to strengthen the walls.

The walls of the Import Dock were constructed with a curved profile which was ideally suited to the shape of the hulls of the East Indiamen.

During World War II the Import Dock played an important role in the construction of the Mulberry floating harbours for the D-Day landings in Normandy, in 1944. After World War II the Import Dock was filled in and a number of new developments, including the Financial Times Print Works (1987-88) and Telehouse Europe (1988-90), were built.

The Lock

The Entrance Lock, with a width of 48 ft, was the largest lock in the Port of London. It had a curved or rounded bottom, unlike the shallow inverts of the locks constructed at West India Docks.

Crystal Palace Dinosaurs

Commissioned in 1852 and unveiled in 1854, the Crystal Palace Dinosaurs are the world's first dinosaur sculptures.

They were designed and sculpted by Benjamin Waterhouse Hawkins, under the scientific direction of Sir Richard Owen. Sir Richard Owen is best known for coining the term 'Dinosauria'.

The sculptures also include other extinct animals and the collection is known as the 'Geological Court' or 'Dinosaur Court'.

By today's standards many of these sculptures are anatomically inaccurate. Many were sculpted on incorrectly assembled skeletons, showing the limit of 19th century scientific understanding. But, being the world's first, they paved the way for many of the advances in fossil understanding and palaeontology.

In 1952 a full restoration of the sculptures began, with some of the dinosaurs being moved. The sculptures were Grade II listed, in 1973. Between 2001-02 the sculptures were extensively restored, with fibreglass models replacing the more severely damaged ones. Some previous restorations had used lead, for the legs, linking these appendages to the bodies with iron rods. The iron had then corroded, causing more damage, resulting in new pieces to be cast. 

In 2007, the sculptures were Grade I listed.

Of the fifteen genera of extinct animals only three are true dinosaurs. The periods that are covered by the sculptures include the Palaeozoic, Mesozoic and Cenozoic.

In May of this year, Crystal Palace Park, the dinosaurs, playground, cafe and more began undergoing a multi-million pound refurbishment, which is due to be completed by summer 2026. The park is remaining open, but restrictions to certain areas may be in place.
