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 🙂


May 15th Open Day

Bit quieter this weekend but so many interesting questions more than made up for the lower visitor numbers. More arrivals from the Netherlands and Germany were the furthest this week, but many locals still attending, many of which have never had the opportunity to visit the tower before.

John G: Impressed by extent of technical description – well done (ex Plessey & EMI Electronics)

Mr & Mrs Herron: Very interesting, great history to show my children.

Ron W: Excellent! very interesting, keep up the good work.

Next open day will be Sunday 29th May 11am to 3pm. If you would like to visit on another occasion or arrange a group visit we will try to accommodate as best we can, subject to availability. Look forward to meeting you soon 🙂
