However, senior British archaeologist Harvey Sheldon, a specialist on Roman London from the Museum of London, has challenged the claim that the site found at Brockley Hill is Sulloniacis. Aside from the evidence of pottery production and some domestic buildings, modern excavations have failed to find any remains of mutationes (stations for changing horses) or mansiones (accommodation for official travellers). Sheldon suggested several alternative locations, particularly one further south in the vicinity of Edgware Road in Burnt Oak Broadway, a location where the Hendon and District Archaeological Society has already found Roman remains nearby.
