Historic Douglas landmark undergoes essential restoration work to secure its future

By ManxRadio Published 28 May 2026

Castle Mona, the iconic former hotel that has stood silent on Douglas Promenade since 2006, is set for significant restoration work. Developer Tevir Developments has submitted fresh planning applications for essential repairs and improvements to breathe new life into this historic building.

Saving Castle Mona: Major Restoration Plans Underway

The derelict Victorian hotel has suffered from years of neglect, but Tevir's latest proposals aim to address the progressive decay that has plagued the structure. The plans focus on critical work including repairs to the central roof above the ballroom, which planners describe as "overly elaborate" and "inherently vulnerable" to water damage—a major concern for the building's long-term survival.

What the Plans Include

  • Essential repairs and improvements to the central roof structure
  • Possible removal of the heavily-altered south-west wing
  • Potential demolition of the rear courtyard section to facilitate future development
  • Collaboration with the Isle of Man Government's registered buildings officer

While some historic fabric may be lost, the planning application notes that both the south-west wing and rear section have already undergone major alterations and lost significant original detailing over the decades. The core building and its front terrace remain registered, and all work must respect the Douglas Promenade Conservation Area, designated in 2002.

A New Future for an Island Icon

Since acquiring the building in 2018, Tevir has been carefully considering sustainable future uses for Castle Mona. While there is a "desire" from the owners to develop the building with a civic function, final decisions on its use are still under consideration. The removal of the rear section would clear the way for modern development while preserving the building's historic heart.

An exciting chapter awaits Castle Mona as restoration work progresses. Visitors and locals alike can look forward to updates once Tevir has concluded its planning exercise—any future proposals will require separate planning and registered building approvals. For now, this beloved Douglas landmark remains a work in progress, with its restoration representing a significant investment in the Island's architectural heritage.
