There was no Manhattan or Manhattanhenge in 356 BC .
It is too simplistic to say that the sun sets at 306.5 degrees on the horizon in London on July 21 356 BC .
It depends where you are in London and the local horizon . As London is mostly flat it would set at that azimuth from many observation points but if you were to the east of one of the hills it would set further south .e.g. if you were at the site of what was to become Mansell St looking towards Cornhill the sun would set at 304.2 degrees .Worse if you were looking from what was to become Estelle Road towards Hampstead Heath it would be 301.1 degrees .
Further there are no shortage of roads in London that will provide an alignment to the setting sun on the same date as Alexander's birthday today or in 356 bc ,the same applies to yours, and my birthday too .Nothing intentional on behalf of the builder .Any sizeable city will have everybody ever born's birthday "encoded " in some street alignment towards the setting sun , it's to be expected ,statistically .
