Doors will be unbolted, tales will be told and minds will be blown this September as thousands of Essex culture vultures get the chance to stride through the keyholes to many of our county’s most treasured buildings…

Think you know Essex? Well think again because this month brings the chance to step back in time and find out why there’s so much more to our county’s buildings than just bricks and mortar.

The Heritage Open Days scheme (HOD), held each September, is the largest festival of history and culture in the country and sees thousands of volunteers across England organise opens days, talks and tours to celebrate the glorious, fascinating and sometimes downright weird and wonderful past of buildings across England – and all for free.

As usual Essex will be playing its part as hundreds of churches, windmills, historic homes, museums and lesser-known spaces and places will invite people in on several dates across the month, to discover the secrets of their past.

The theme of the HOD 2024 event is ‘Routes Connections and Networks’ and events and activities will range from in person walks, talks, fairs and displays to online lectures and podcasts.

If you’re an ancient history buff or are glued to Amazon Prime’s new sword and sandals drama ‘Those About to Die’ starring Anthony Hopkins, you’re in luck as plenty of Roman-themed events are listed around Colchester- the oldest Roman city in the UK.

Meanwhile some of the county’s oldest churches will be allowing visitors to climb their belltowers while historic homes and mansions will be displaying some of their rarely-seen objects.

Other key events will include a heritage fair organised by the Essex Industrial Archaeology Group (EIAG).

The group hosts a fair every two years, always at a different historic location around the county.

This year the chosen venue is Grange Barn in Coggeshall. Set to be held on September 14 the fair will feature stalls, displays and talks from organisations around Essex that have a passionate interest in the industrial heritage of the county.

'So far for this year we have 20 exhibitors coming covering such industries as textiles, engineering, shoe making and radio communications. There will also be four speakers presenting short talks on metal working, spinning and weaving in Essex during the 20th century,' explained Tony Crosby, chairman of the EIAG.

'There will also be opportunities to visit a restored village smithy, the Coggeshall watermill and the museum and to follow a self-guided walking trail of the industrial sites of Coggeshall.'

Tony continued: 'We aim to have an exhibition representing a wide range of Essex’s industrial heritage. In the past this has included brick making, museums, windmills, water, transport, industrial air raid shelters, railways and historical books.'

Tony is rightfully proud of Essex’s reputation when it comes to industry and innovation- and who can blame him? Many bright sparks have called Essex home at one time or another- from radio genius Guglielmo Marconi to celebrated electrical engineer Rookes Evelyn Bell Crompton, mathematician and clergyman, Dr John Pell (who came up with the mathematical sign for division that we still use today) and farmer Thomas Darby who invented the ‘Darby Digger’, (a stream powered ploughing machine).

It may be news to you also that the world's first hot and cold drinks dispenser was even invented in Saffron Walden. Named ‘the Wonderful Barrel’, it was created in 1696 by Henry Winstanley, a notable local inventor who worked at Audley End for a time.

But these names are just a drop in the well of industrious ingenuity that Essex has boasted.

'These Fairs are biennial and this year will be the fifth we have held at various venues across the county since 2015,' added Tony.

'The aim of the fairs are to raise the profile of Essex's industrial past as the county is so often seen as being only agricultural and nowhere near as industrial as some of the midlands and northern counties. However we have been home to many nationally important industries such as agricultural engineering, silk textile weaving, metal window making, electronics, radio communications, and ball-bearings.

'We always get people telling us that they never could have imaged that Essex history is so rich in industry.'

As part of the HOD scheme and industrial fair there will also be the chance for visitors to check out Henry ‘Dick’ Nunn's smithy based in East Street, Coggeshall. As well as being the village blacksmith during the Victorian era, Nunn was a social campaigner and champion of working people.

He had an extraordinary life. His mother died of smallpox when he was three and then his father perished due to Tuberculosis. At just 18 years old Dick found himself having to be the sole provider for his family.

The smoke-stained walls, dusty bellows and heat-cracked hearth inside his blacksmith’s forge mean the site is almost exactly how it was left when Nunn died in 1896.

The Smithy will be open to visitors from September 14-15, from 11am-4.30pm each day.

Meanwhile in south Essex, Rayleigh Town Museum will be hosting a travel themed event to coincide with the theme of this year’s HOD

The museum – based in High Street, Rayleigh- will be welcoming in visitors from September 13-15 to see its Essex County Maps display. More than 40 maps will be on show, dating all the way back to the 1600s, including the famous Chapman and Andre Essex maps of 1777.

Museum chairman Mike Davies said: 'Heritage Open days are a wonderful opportunity to showcase Rayleigh’s rich and varied history and heritage. We always try and do something extra special, and this year is no exception with this wonderful visual display on maps of the county of Essex.

'We have the first A/Z map of Essex showing Rayleigh dating to 1675 known as Ogilbys Road Map, as well as small globes and atlases of the world. Another interesting exhibit will be Second World War RAF officer’s escape map in the form of a framed handkerchief!'

Mike added: 'Some of our most popular artefacts are some large-scale Ordnance Survey maps of Rayleigh dating to the 1950’s showing EVERY house in Rayleigh. Some visitors note that 70 years ago their road was not even built let alone their house. It shows just how rural Rayleigh was in living memory.'
