Long thought to have been London’s oldest public statue (and certainly the oldest of a monarch), this statue of Anglo-Saxon King Alfred the Great stands in a quiet location in Trinity Church Square in Southwark.

The statue – which depicts the bearded king robed and wearing a crown – was believed to have medieval origins with some suggesting it was among those which north face of Westminster Hall since the 14th century and were removed by Sir John Soane in 1825.

But recent conservation work has shown that half of the statue is actually much older. In fact, it’s believed that the lower half of the figure was recycled from a statue dedicated to the Roman goddess Minerva and is typical of the sort of work dating from the mid-second century.

Measurements of the leg of the lower half indicate the older statue stood some three metres in height, according to the Heritage of London Trust. It is made of Bath Stone and was likely carved by a stone worker located on the continent. It probably came from a temple.

The top half, meanwhile is made of Coade stone and, given that wasn’t invented by Eleanor Coade until around 1770, the creation of the statue as it appears today is obviously much later than was originally suspected which may give credence to theory that it was one of a pair – the other representing Edward the Black Prince – made for the garden of Carlton House in the late 18th century.

Putting the two parts of the statue together would have required some specialised skills.

The Grade II-listed statue has stood in the square since at least 1826. Much about who created it still remains a mystery. The fact it incorporates a much older statue means the question of whether it is in fact London’s oldest outdoor public statue remains a matter of some debate.
