Rather wet open day

Unfortunately, we had our wettest and least attended open day to date. We stayed at our post and welcomed four hardy visitors. Two from Reading and 2 from the Netherlands, where many of our visitors arrive from. Being only a few miles from Parkeston Quay, where the ferry from the Hook of Holland docks, we are a favourite stop off point for people entering or leaving the UK. We still received positive feedback which is always good.

Jamie – Great!

Kees B – Interesting & stunning

Our next open day is Sunday 12th May between 11am and 3pm. Entry is free but donations are always welcome. If you haven’t visited the Radar tower since 2021, we have added many artefacts and have installed interpretation panels explaining the tower and how it worked. Hope to see you soon at this unique survivor from WWII 🙂


First Open Day

A big thank you to all those who came along today for our first open day of 2024. We had 22 visitors, which is slightly up on our first day last year, and some great feedback.

Kim + Sam – Very interesting. We’ll be back with more family.

Catey + Clive – Amazing place, excellent displays, we will be back. Well done.

Zoe & Phil – really interesting!

It always makes it worth while when receiving these sort of comments. We strive to present this historic building in a clear and concise manner with a good balance of technical and local information. We open again at 11:00 on Sunday 28th April. Hope to see you there 🙂


First Open Day 2024

We have swept and cleaned the tower ready for our new season, beginning at 11:00 on Sunday 14th April. A couple of new exhibits for this year include models of the Maunsell Forts located off the coasts of Essex and Kent. His Majesties Fort Roughs Tower can be seen from the middle floor of the radar tower, more commonly known today as the Principality of Sealand. This was home to Joan and Roy Bates from 1967 and is still owned by their son Michael.

Our other new model shows the Chain Home Radar site located at Walton on the Naze, 5 miles south of Harwich. Only one building remains today, the rest having fallen off the cliffs since WWII due to coastal erosion.

We will be opening every other Sunday until the end of October this year. Group and private visits are possible (subject to availability). Please contact us via our contact page. If you haven’t visited before, we hope to meet you this year 🙂


Open Days 2024

Work is underway to reopen the Harwich Radar Tower in April 2024. Our first open day will be Sunday 14th April between 11am and 3pm. Entry is still free but all donations are welcome.

During the winter we have been adding to the items displayed in the tower. A model of the Radar site located at Walton on the Naze has been installed showing the layout of the site during WWII. Very little remains of the site but the original entrance can still be seen, along with parts of the concrete bases that once supported wooden huts.

If you have been to the tower before, we always welcome return visits. If you haven’t been yet, then please come along to this unique survivor from WWII. The only remaining ‘Minewatch’ Radar site in the UK open to the public, housing possibly the only surviving Type 287 aerial array in the world.


Last Open Day of 2023

Sunday 29th October is our last open day this season. We are open between 11am and 3pm as always. Admission is free but donations are always welcome. We can open on Sundays throughout the year for group bookings but you must contact us first to arrange time and date to ensure availability of a volunteer to open up (usually me lol) A few new bits are planned for next year so if you haven’t been along to see us this year, we hope to see you in 2024 🙂


Busy May at the Radar Tower

May 2023 has proved to be a busy month here at the Radar Tower. A busy weekend at the beginning of May, a school visit, a visit from the ex-friends of the Imperial War Museum and another busy weekend to close the month.

St Philomena’s Catholic School, Frinton visited us on 10th May with 2 staff and 18 year 6 pupils. Following a visit to the tower, they were also shown around Beacon Hill Battery next door.

“Children (and adults) thoroughly engaged by an excellent tour from Peter (Curator). A great visit for our work on WWII – so informative”

The ex-friends of Imperial War Museum visited Harwich Redoubt, Radar Tower, Treadwheel Crane and the Electric Palace before walking to the seafront to visit the Kinder transport Memorial on the quay side by Ha’penny pier.

The last open day of May was our busiest so far this season with 73 visitors from far and wide including San Francisco, Manchester and Nottingham.

F Morgan – well researched, nice time

Mason Family – Very interesting and impressive history

Lindsey & Matt – Very interesting history, good exhibits, very informative

Our next open day is Sunday 11th June between 11am and 3pm. As always, entry is free but donations are always welcome. Please come and visit us at this unique survivor from WWII. Hope to see you there 🙂


Open Day: April 30th 2023

Our best open day so far this year, with 64 visitors between 11am and 3pm. Some interesting questions, as always, and several positive comments. One visitor was impressed with the amount and balance of information available in the tower. He also appreciated the panel ‘what can you see?’ which can be found in the operations room on the middle floor. It shows photographs of what can be seen on the other side of the estuary, outside Landguard Fort.

Bethany R: Awesome to learn about local history

Allison M: I’m a Harwich girl, first time in having a look around. Really interesting

Fleur: Hidden Gem!

The tower has been an interesting journey for us, learning about Radio Direction Finding (Radar) and trying to represent the tower how it may have been seen in WWII. We are still sourcing material and information so hopefully it will continue to improve. Next open day Sunday 14th May, 11am to 3pm. Hope to see you there 🙂


Subterranea Britannica Site Visit

On Saturday 24th September we had a visit from Subbrit who spent a day with us in Harwich. The morning was shared between the Harwich RDF Tower and Harwich Redoubt before a well earned lunch break.

The afternoon saw us all in Beacon Hill Battery looking round the many structures that have survived from late Victorian, 1901, WWI and WWII. The battery retained its weapons right up until 1956 when it was finally stood down with the cessation of Coastal Defence.

Beacon Hill Battery will remain open throughout the winter every Saturday and Sunday between 10am and 4pm. This will be dependent on weather so please check availability before setting out if travelling from some distance away.

Some positive feedback received at the RDF Tower:

Zamojoa Family: Not expected at all !!! 🙂

G Ward: A lot more to see than I expected. The Harwich ‘Tardis’

Webb Family: A well kept secret ! Interesting

We have two more open days this year, Sunday 9th and Sunday 23rd October between 11am and 3pm. Free admission but donations welcome, hope to see you there 🙂


Our first years open days: 2021-2022

On June 27th 2021, we opened our doors for the first time following a major refurb and we haven’t been disappointed with the response. As of June 26th this year, we have met 873 visitors during 20 open days, an average of 43.6 guests per day. We would like to thank all those who have visited over the past year.

Rob & Sue: “very good” thank you

Tadana & Derrick: Very interesting

Dave & Sandra: Interesting

We will be opening again on Sunday 24th July between 11am and 3pm. We also have a two day event in September when we open the doors for the Heritage Weekend event on Saturday 10th and Sunday 11th, again between 11am and 3pm each day. Hope to see you there 🙂


Much drier open day: Sunday 12th June

Was nice to be able to sit in the sunshine to welcome visitors outside yesterday. A steady flow of visitors from the time we opened the gate until we closed, 41 in all. Coventry was the furthest this week, followed closely by Northampton and a lot of interesting questions. Still receiving positive feedback too:

Bernard O: Wonderful effort

Richard P: Fantastic exhibits

Christina P: Great! Well done

Still adding small bits each week, trying to build up a picture of what life would have been like serving in the RDF Tower. Been an interesting project so far and looking forward to opening again on Sunday 26th June between 11am and 3pm – Admission free, Donations welcome 🙂
