A wedge-shaped painted hornet, head down and stinger up, mounted on a steel column at the north end of the High Street near the Harlequin Shopping Centre. It is one of half a dozen public-art sculptures dotted around the centre and is the only one most visitors photograph.
The hornet is a nod to Watford FC, whose nickname is "the Hornets" and whose grounds are at Vicarage Road a short walk south. Easy to miss if you don't look up — the head is about four metres off the pavement.
