Medway Council has surrendered operational control of Upnor Castle back to English Heritage. The prominent Elizabethan gun fort, which sits on the banks of the River Medway in Kent, reopens to the public this Sunday. However, the administrative handover brings a major contraction in public access.

Beginning 31 May, the 16th-century fortification abandons its traditional six-day-a-week seasonal opening schedule. It moves instead to a highly restricted monthly framework. Members of the public can now only see the inside of the monument by booking one of two guided tours. These will run exclusively on the final Sunday of each month. The drastic operational overhaul ends decades of local authority control. It signals a shifting landscape for regional heritage conservation across the United Kingdom.
The Financial Realities Behind the Handback
Local authorities across Britain are facing severe financial strain. Medway Council is no exception. To balance its books, the cabinet voted to terminate its long-standing Local Management Agreement with English Heritage. This contract previously allowed the municipality to run Upnor Castle, Rochester Castle, and Temple Manor as a combined tourist portfolio. While the council chose to retain custody of the highly profitable Rochester Castle, it decided it could no longer justify the overheads required to run Upnor or Temple Manor.
The numbers explain the decision. Council records reveal a steep drop in footfall at the riverside fort. Visitor numbers plunged from 19,003 during the 2023/24 financial year to just 13,000 in the subsequent twelve months. For a council looking to rationalise its cultural budget, maintaining an under-visited site became impossible.
The restructuring directly impacts local jobs. Two permanent staff members currently handle the castle’s day-to-day operations. Under the terms of the new agreement, these workers will transfer from municipal employment to English Heritage. The transition complies with standard Transfer of Undertakings (Protection of Employment) regulations, commonly known as TUPE.
What the New Visitor Experience Looks Like
The days of spontaneous afternoon strolls through the castle’s courtyard are over. The new regime replaces open admissions with a tightly managed, pre-booked itinerary. English Heritage has confirmed that the monthly Sunday tours will start strictly at 1:00 pm and 3:00 pm.
This model changes how the community interacts with its local landmarks. The castle will no longer function as an accessible community park or a casual weekend destination. Instead, it transitions into a protected monument with highly regulated entry. English Heritage frequently uses this strategy for fragile or remote architectural structures to keep staffing costs low.
A Disappointing Compromise for Local Tourism
The shift has caused concern among regional tourism advocates. Initial council briefings revealed that English Heritage originally intended to keep the site open for regular seasonal visits from April through October. The final operational plan, however, abandoned that goal in favour of the twice-a-month tour model. Critics argue that this reduction in hours effectively removes Upnor Castle from Medway’s active heritage trail.
A Fortress Born of Elizabethan Anxiety
To understand the Upnor Castle’s architectural significance, one must look back to the geopolitical tensions of the 16th century. Queen Elizabeth I ordered the construction of the fort in 1559. Her engineers designed it specifically as an artillery piece to protect Royal Navy warships. These vessels anchored nearby in the reaches of the Medway and at the fledgling Chatham Dockyard.
The site features a distinctive triangular gun platform that juts directly into the river. This design, combined with its elegant turreted facade, makes it one of England’s most visually striking pieces of military architecture.
The Humiliation of 1667
Despite its defensive design, the castle is most famous for a catastrophic failure. In June 1667, during the Second Anglo-Dutch War, Admiral de Ruyter led a daring Dutch fleet up the River Medway. The poorly supplied gunners at Upnor Castle offered little resistance.
The Dutch raiders breached the defensive chain, capturing or burning several of the English Navy’s finest warships at Chatham. The incident remains one of the most humiliating defeats in British naval history. It exposed deep flaws in coastal defence strategies and forced a complete rethink of how the nation protected its fleet.
Capital Investment Under New Stewardship
While public access is shrinking, English Heritage insists the handover will secure the long-term structural future of the site. The charity has announced a series of capital improvements designed to modernise the fort’s aging infrastructure.
The planned upgrades include:
- A complete refurbishment of the on-site gift shop located inside the ticket office.
- The introduction of a new food and drink concession for visitors.
- Upgrading the old till systems to integrate with modern digital ticketing networks.
- Replacing faded historical interpretation boards with new educational displays.
- Installing a network of CCTV cameras to improve security across the grounds.
Public Consultation and Booking Procedures
The incoming management team acknowledges the local unease surrounding the new hours. To address these concerns, English Heritage will hold a community open morning on Saturday, 13 June. The event runs from 11:00 am until 1:00 pm. This session gives neighbours and local historians a chance to meet the caretakers and discuss preservation plans.
For those wishing to attend the inaugural tours this Sunday, spontaneous arrival is not an option. English Heritage requires all visitors to secure their slots in advance. The charity is managing all ticket allocations through its official website.
