The Vikings are coming!
But no need to lock up your daughters. This lot will be friendly when they set up their Viking camp in Central Park on Saturday and Sunday, July 7 and 8.
The scene may sound a bit scary - the heathen army led by Iver the Boneless - is marching on East Anglia in the year 866AD.
Their encampment in Boston has been befriended by locals who have provided horses.
There will be free entry to the event, from 10am to 4.30pm, when typical Viking activities will be under way - cooking in the food tent, have a go at hand-grinding corn, games, preparations for a fishing expedition, spinning wool and weaving, nuns and monks practising calligraphy with a chance to produce your own illuminated manuscript, strike your own Viking coin, see the village blacksmith at work, music from period instruments, woodworking, the chandler making tallow candles and instruction from the surgeon (not for the faint hearted!).
The armoury will be open, with a chance to handle some of the real fighting implements and there may be battle re-enactments.
