Introduction

Every September, thousands of historic buildings, museums, gardens and hidden corners across England throw their doors open for free as part of Heritage Open Days 2026, the country’s largest festival of history and culture. This year’s festival runs from Friday 11 to Sunday 20 September 2026, and the theme is “Everyday Histories” – the stories of the ordinary people and communities who shaped the places we live in.

Heritage Open Days in Northumberland and the wider North East is one of the best weeks of the year for a cheap day out. Places that normally charge £15 or more per adult are free to walk into, and in most cases you don’t need to book. Here’s our pick of what’s on locally, starting with Northumberland and then heading over the border into Tyne & Wear and County Durham.

“The big National Trust places – Gibside especially – get very busy on the Saturday of Heritage Open Days. Get there for opening, or pick one of the weekday dates if you can. And if you’re heading to Holy Island, check the causeway crossing times before you leave the house, not when you get to Beal.”

Vanbrugh’s Baroque masterpiece near Whitley Bay is free to all on the opening weekend of the festival. Explore the house and its portrait collection, wander the late-summer gardens and drop in on one of the potted-history or garden tours. There’s also the chance to visit the nearby Church of Our Lady and hear about its Lottery-funded restoration.

  • Where: Seaton Delaval Hall, The Avenue, Seaton Sluice NE26 4QR
  • When: Friday 11 and Saturday 12 September, 10am–5pm
  • Cost: Free admission for everyone (normally around £16 per adult)
  • Booking: Not needed – just turn up
  • More info: Seaton Delaval Hall on the National Trust website

The Trevelyan family home near Morpeth opens free for two days, with the house, walled garden, woodland and riverside walks, play areas and the Dragon cycle trail all included. If you’ve never been, this is a big estate – give yourself the whole day and take a picnic.

  • Where: Wallington, Cambo, near Morpeth NE61 4AR
  • When: Sunday 13 and Monday 14 September, 10am–5pm
  • Cost: Free admission
  • Booking: Not needed. The Monday is a good bet if you want it quieter
  • More info: Wallington on the National Trust website

The birthplace of engraver Thomas Bewick at Mickley, near Stocksfield, is a small, charming site in the Tyne Valley with a cottage, farmyard and printing demonstrations. Ideal if you want something quieter and closer to home for Hexham, Prudhoe and Consett folk – it’s only twenty minutes up the road from us.

  • Where: Cherryburn, Station Bank, Mickley, Stocksfield NE43 7DD
  • When: Friday 11, Thursday 17 and Friday 18 September – check the Heritage Open Days listing for exact hours

  • More info: Cherryburn on the National Trust website

The Lutyens castle on Holy Island is free on the final weekend, including the Gertrude Jekyll garden, the lime kilns and the shoreline walks. The usual Holy Island warning applies: check the safe crossing times for the causeway before you set off, and remember it’s about a mile’s walk from the car park to the castle.

Aerial view of Alnwick town centre and Alnwick Castle, Northumberland

Alnwick has organised a full day of openings on the 19th. Bailiffgate Museum & Gallery is free, and you can also get behind the scenes at the Mechanics’ Institute, the Town Hall (the Freemen’s meeting place for over 250 years), the former House of Correction on Green Batt and the Lucy Bronze Clubhouse at Alnwick Town Juniors. There’s also a pop-up exhibition on the town’s industrial history at the former council offices, and the Aln Valley Railway is running guided tours of its engine shed and museum the previous Sunday (13th).

  • Where: Various venues around Alnwick town centre
  • When: Mostly Saturday 19 September; Aln Valley Railway Sunday 13; the “lost pubs of Alnwick” walk is Thursday 17
  • Cost: Free
  • Booking: A few things need booking in advance – the Alnwick Playhouse backstage tours, the Alnwick Garden heritage tour and the lost pubs walk – so check the Heritage Open Days website first

Berwick-upon-Tweed Old Bridge over the River Tweed with the Royal Border Bridge behind

Berwick Barracks, the English Heritage site currently being transformed into a new museum, is running behind-the-scenes construction tours and an exhibition on the Main Guard across the whole ten days. Elsewhere in town there are talks on Berwick Cockles (the town’s 200-year-old peppermint sweet) and Anglo-Saxon costume, a guided walk through Berwick’s brewing and malting past starting from the Pilot Inn, the 18th-century Bankhill Icehouse and a 70-year photographic archive at the Record Office.

A few more worth knowing about, all free and all walk-up unless stated:

  • Woodhorn Museum, Ashington – Saturday 12 September
  • Newbiggin Maritime Centre and the 1866 Rocket House – Thursday 17 and Friday 18 (10am–4.30pm) and Saturday 19 (11am–4.30pm). Fully accessible, and one of the earliest rocket houses in the country
  • Heatherslaw Corn Mill, near Ford – Saturday 19 and Sunday 20 September
  • The Chantry, Morpeth – Saturday 19: poets in costume telling the town’s history
  • Quaker Meeting House, Allendale – Saturday 19: a meeting house and burial ground in use since the 1660s

Red kite in flight – a regular sight over the woodland at Gibside

Just over the county line near Rowlands Gill, and probably the biggest draw in the region. The National Trust’s 600-acre Georgian landscape garden is free for three days, with the Palladian Chapel, the Column to Liberty, the walled garden, the woodland trails (keep an eye out for the red kites) and the adventure play area all included. There are crypt tours under the Chapel running through the day on a first-come, first-served basis.

  • Where: Gibside, near Rowlands Gill, Gateshead NE16 6BG
  • When: Friday 11 to Sunday 13 September, 10am–5pm (last entry 4pm)
  • Cost: Free admission – normally around £14 per adult, so a decent saving for a family
  • Booking: Not needed. Expect it to be busy on the Saturday – arriving for opening is a good shout, and mobility trampers and the access bus are available
  • More info: Gibside on the National Trust website

Free entry to the whole museum for the weekend, which is a serious saving. Alongside the galleries there are guided tours of the museum and grounds, Vault Tours, Silver Swan performances, object-handling sessions, artist-maker workshops and a family trail put together by the museum’s young volunteers. The Norman Cornish exhibition – everyday life in the North East, which fits this year’s “Everyday Histories” theme perfectly – is on too.

  • Where: The Bowes Museum, Newgate, Barnard Castle DL12 8NP
  • When: Saturday 12 and Sunday 13 September, 10am–5pm
  • Cost: Free entry for all
  • Booking: Not needed – just arrive
  • More info: Heritage Open Days at The Bowes Museum
Durham Cathedral and Castle above the River Wear

If you’re happy to travel a bit further, there’s plenty more across the region:

  • Durham Castle – Saturday 12 September
  • Souter Lighthouse – Tuesday 15 and Saturday 19 September
  • Crook Hall Gardens, Durham – Wednesday 16 and Saturday 19 September
  • Newcastle Castle – Thursday 17 September
  • Washington Old Hall – Friday 18 and Sunday 20 September
  • Jarrow Hall and Segedunum Roman Fort, Wallsend – Saturday 19 and Sunday 20 September
  • More info: Search all North East events on the Heritage Open Days website

Almost everything above is walk-up and free, but the bigger National Trust sites will be busy on the weekend days, so go early or pick a weekday opening if you can. Where a tour needs booking, spaces tend to go quickly once the festival starts. Car parking is generally still charged at National Trust properties for non-members, so factor that in. And for the full, searchable list – including plenty of smaller village churches, halls and walks we haven’t had room for – head to heritageopendays.org.uk.

Dates and times were all checked against the official listings when we wrote this, but venues do occasionally tweak their hours, so it’s always worth a quick look before you set off. TWDA is based in Northumberland and we work with a lot of tourism and hospitality businesses across the region, so we’re always happy to see the North East showing itself off. If you make it to any of these, we’d love to see your photos.
