London has been around for at least two and perhaps three thousand years, with no charter dates that I can establish. The Romans named it Londinium around 50 AD when Pluto was in Capricorn and Neptune in Pisces, so it is returning full cycle at the moment.
There are two dates which may be significant in more modern times. 1 April 1965; and 9 September 1835.
The 1965 chart does have a difficult and volatile Mars Uranus Pluto opposition Saturn square North Node in Gemini; and a high-finance Jupiter in Taurus opposition Neptune. Tr Neptune has been undermining that 1965 Mars Uranus and Saturn by opposition and conjunction through 2016, perhaps an indication of the Brexit panic, since 60% of Londoners voted to remain. And those influences recur mid October this year to early Jan 2018. At the moment tr Neptune is opposition the 1965 Pluto, at the same time as the Progressed Mars is conjunct the 1965 Pluto – so a double whammy from a destructive and dangerous Mars Pluto along with high confusion from Neptune. The progressed Mars will take its time in moving off that conjunction since it only moves at a degree every two years. In addition, the February 2017 Pisces Solar Eclipse was conjunct the 1965 Saturn and opposition Uranus Mars. Eclipses on Saturn are usually when chickens come home to roost and a price has to be paid for past mistakes.
The 1835 chart, which was a previous reorganisation of the city, has tr Pluto square the Solar Arc Mars, exact at the moment. And is in a longish run of difficult aspects with tr Pluto square the 1835 Mars last year over Brexit and moving across the square to the Mars/Saturn midpoint now, and thence onto square the 1835 Saturn in 2018/19 as economic woes start to build. So a time of high-risk and hardship.
The Great Fire of London in September 1666, which destroyed 90% of the houses of the 80,000 inhabitants, followed on from the plague of the winter before which had killed a quarter of London’s population. When the 1666 fire occurred, the Sun was opposition Jupiter square Pluto; with Mars in Scorpio trine Jupiter, sextile Neptune Saturn in Capricorn and square Uranus. With Mars just a degree away from an opposition to Algol. So Jupiter again acting as a fuel for disaster, amplified by Pluto; with a malignant Mars causing additional havoc.
London has survived with stalwart resilience through many horrors during its long history. In the 20th Century: the Blitz in WW11 (started with Uranus conjunct Algol); the years of the IRA bombings; into the 21st Century the Islamic fundamentalist attacks. Both the 1965 and 1835 charts have Mars Saturn and Pluto in aspect, which gives grit and perseverance, resourcefulness in the face of danger. Admittedly those aspects will tend to attract situations which draw on exactly those characteristics, but it will always rise to the challenge.
