The Beaulieu Dairy House: Britain’s Best Disguised Pillbox

Beaulieu dairy house pillbox

The picturesque village of Beaulieu in the New Forest had a very interesting part to play during WW2. As well as being just down the road from the RAF Beaulieu Airfield, D-Day landing craft were assembled on the river, and the secret Special Operations Executive was heavily active on the Estate. 

But it also had some of the most imaginative plans to help slow down a German invasion if the enemy was to use the river as an invasion point. The plan was in the form of various secret pillboxes and shooting positions, each covering every conceivable angle of approach from the river, road, or bridge.

One of the more impressive secret pillboxes is the converted Dairy House on the grounds of the Beaulieu Mill House, set the river and bridge. I believe the Dairy House to be the best disguised pillbox in the whole of Britain – I’ve never seen anything quite like it.

In April of 2021, I was given permission by the Beaulieu Estate and Mr Phipps who lives in the Mill House, to come and look at the Dairy House pillbox to document it and share what I uncovered. 

On that day I was able to take photos of both the outside and inside of the Beaulieu Dairy House, including a video tour which you can also see above. 

The secret pillbox built-in to the Old Dairy House in Beaulieu

As you travel into Beaulieu using the Palace Road approach from the Hill Top end, you will start to curve around the road towards the bridge. If you look to your left, you might have seen an old building with a round and pointy roof to it.

This is the view of the Old Dairy House from the bridge as you enter Beaulieu.

The building is the Beaulieu Dairy House and I believe it originally dates from the 1700s. 

Each day people drive past it without giving it a second thought. In fact, locals have told me they have passed it hundreds of times and never known the secret that it holds: it was converted into a WW2 pillbox in 1940.

I have personally never seen anything like this, and don’t think there’s a pillbox like it anywhere else in Britain. 

Whilst there was a concerted effort to disguise pillboxes during the Second World War, I believe this to almost be a one-off in terms of how it looks and has been camouflaged.

Only when up close and looking at the windows of the Dairy House does the World War 2 pillbox become clear.

The reason why Beaulieu village was chosen to have a defence like this was because it was feared that the New Forest coastline could be a point of invasion. In Beaulieu village there are other hidden pillbox positions too – I will document those here in the future so please visit back. 

If the enemy had landed on the New Forest beaches, the Beaulieu River and roads would have been used to travel deeper into the UK and Hampshire. 

As a result, multiple positions and plans were made to defend various aspects in the village; the Beaulieu Dairy House pillbox being one of those, with the conversion happening around 1940.

When inside Beaulieu’s Old Dairy House you can see how well constructed and crafted the internal hidden pillbox was.

The Beaulieu Dairy House is a listed building and was originally used to store milk and make butter. I believe there could be another dairy house structure like this on the Beaulieu Estate, but unlike this one, it wasn’t converted into a WW2 pillbox. 

As you look at the exterior of the Beaulieu Dairy House, there are a few things of note before looking at loopholes. 

Old Dairy House in Beaulieu
To the casual observer, the Old Dairy House in Beaulieu is just a quaint old building… but it holds a wartime secret.

Firstly, the tiles on the roof had to be replaced in 1997 due to age. The wooden struts that hold the roof up were also replaced that year, I believe due to deterioration and weakening. The struts were made from fallen oaks trees that came down in the great storm of 1987.

The tiles and wooden support struts were replaced in 1997 to help preserve the Dairy House… and the secret pillbox inside.

As you walk around the exterior of the Dairy House pillbox you will find 3 loopholes in total. Each gives a different view of a possible invasion route through the village.

The first loophole looks out over the bridge that provides an access point in and out of Beaulieu village. It’s said that this bridge would have been rigged with explosives to also help slow the enemy advance – it was also widened in 1943 to let Allied vehicles, possibly tanks drive over it.

This pillbox loophole offers a fantastic view of the bridge that comes into Beaulieu.

See how the most of the window has been bricked up behind the glass. You will also see how the glass has been removed from the window to allow a clear line of fire through the slit. 

The second loophole looks towards the road and walls of the Beaulieu Palace House. Incidentally, loopholes have also been cut into the walls of the Estate to also provide firing positions.

This loophole looks out towards the road and palace walls. You can see how neatly the glass has been taken out of the window to allow for an easier firing position.

The third and final loophole overlooks the river as it flows into Beaulieu Village. As with any of the positions covered by the Dairy House’s secret pillbox, this could have been an invasion point for troops entering Hampshire.

This pillbox loophole window overlooked the approach into the village down the Beaulieu River.

As you can see with all three loopholes, they are very hard to see, even when you’re stood directly outside the Dairy House, they are not obvious. It’s a great disguise.

Even when stood a few feet away from the Dairy House, it’s not easy to see the disguised loopholes behind the pillbox windows.

Moving inside the Dairy House pillbox, it’s clear to see how well protected it was intended to be. The door is the first sign of this, as it’s possible to see how the walls have been made a lot thicker than they were originally made to be.

You can just about make out the original wooden door frame, which was then replaced with thicker walls entering the Dairy House pillbox.

As you walk through the door, you clearly see the wooden surround of the original door, before the 1940 brickwork was put in. See how the walls are now between 2 and 3 feet thick upon the conversion.

But the entrance as you see it today, has actually changed slightly from how it was when the Beaulieu Dairy House was converted into a pillbox during WW2. 

The 1940 entrance would have been lower. In the 1990s, a brick section was taken out to make the entrance taller, meaning access into the Dairy House was easier. The area where you see the cement, is where the bricks have been taken out post-war.

Here you can clearly see the old and original wooden door frame, then the 1940 changes with a deeper and thicker wall and entrance. Where the cements ends is where the bricks were taken out in the 1990s to make the entrance easier to access.

Then inside the Dairy House, you will also notice a low ceiling. This concrete roof was also put in during the 1940 pillbox conversion for added protection.

The hole cut into the roof section was also made in the 1990s. This entrance was cut in order to allow for felting of the roof to help waterproof and protect it.

This hole was cut into the concrete roof of the internal pillbox in the 1990s to allow for felting of the roof inside.

You can also see how thick the walls are by looking at the loopholes from the inside of the pillbox, and how thick the slit entrances are.

This view from a loophole towards the Beaulieu River bridge shows just how thick the walls were made in 1940 when the WW2 pillbox conversion was completed.

The Beaulieu Dairy House pillbox was designed to have 3 men using it, and this is noted on a defence plan of the village drawn up Lieutenant Colonel Crofton in 1942. Crofton was 2nd in command of the Home Guard’s 9th Forest Battalion.

This cutaway of a diagram drawn by Lieutenant Colonel Crofton in 1943 and shows the Diary House and other defences in Beaulieu Village.

He wrote in his notes that the plan for the Home Guard was to fight until the death to protect and slow down the enemy before reinforcements arrived.

Thanks & notes

The Old Dairy House is on the property and garden of the Mill House in Beaulieu. The Mill House is private property and owned by the Beaulieu Estate. It is not publicly accessible.

I feel privileged to having been allowed to visit the property, and would like to offer a huge thank you to Mr Phipps for being so accommodating and welcoming to me.

Unless you were inside the Dairy House, it’s unlikely you know what secrets it holds.

I would also like to thank the following people who made my visit possible, and allowed me to research and bring you this information on what I believe to be the best disguised pillbox in Britain.

  • Mr Phipps at the Mill House for his hospitality and knowledge
  • The Beaulieu Estate & Lord Montagu
  • Lesley at the Beaulieu Estate for helping organise permissions
  • The New Forest National Park Authority: their website contained a lot of background information.
  • Sir Lieutenant Colonel Crofton & family: his diagrams helped me understand why this secret pillbox was here.
