Alnwick Garden and Treehouse Northumberland wedding venue

Alnwick Garden and Treehouse is a wedding venue I am familiar with, having visited several times. I have spent time in the gardens, eaten in the Treehouse restaurant, second shot a wedding in the Treehouse, and I have a wedding later this year in the Pavilion.

It is a truly unique wedding venue in the north East of England, and I can't believe that it has taken me so long to review it.

Alnwick Garden is adjacent to Alnwick Castle in Northumberland. The first Duke of Northumberland employed the renowned Northumberland gardener Capability Brown to lay down the gardens. Under subsequent Dukes, the gardens grew in size and scope until the Second World War, when the garden was turned over to food production. The gardens fell into disrepair after the war.

The redevelopment of the gardens began in 1997 and cost £42 million. A large water cascade, the Grand Cascade, was built, the gardens reconstructed, and this was followed by the Treehouse in 2004. The poison garden followed in 2005, and the pavilion and visitor centre in 2006.

Weddings at Alnwick Garden and Treehouse

There are two main locations where weddings take place at Alnwick Garden; the pavilion and the Treehouse.

Pavilion Weddings at Alnwick Garden

Ceremonies take place in a light and contemporary space overlooking the gardens. With its glass walls and high ceiling, you can enjoy the panaromic views and beautiful colours of The Garden in bloom - depending upon the season of course.

The Pavilion Room can hold civil marriages and civil partnerships for up to 150 guests, with celebratory drinks served on the terrace.

Up to 500 guests can join the party, with dinner overlooking the Grand Cascade followed by dancing under the stars and above thousands of twinkling lights on The Pavilion’s terrace.

For an additional charge, the Grand Cascade can be lit and set to music, and the terrace lights can be given a chosen colour.

Treehouse Weddings at Alnwick Garden

Stowed beneath the woodland canopy, the Alnwick Garden Treehouse is most suitable for an intimate ceremony.

Wrapped in thousands of tiny lights and warmed by a roaring log fire, the Treehouse creates a uniquely romantic setting.

The Treehouse is perfect for smaller civil marriage and civil partnership ceremonies for up to 60 guests and can comfortably provide a seated meal for up to 85 people. There is private decking, bar facilities and walkways providing intimate reception and entertainment areas, as well as picturesque settings for your wedding photographs. The Roost is a great space in which to customise your theme.

Wedding Photography at Alnwick Garden Pavilion and Treehouse

I will be photographing a wedding in the Pavilion later this year, so I can only talk about photographing the Garden and Treehouse here. 

Of course, Alnwick Garden and Treehouse offer a unique and exciting opportunity for wedding photography. The backdrops and scenery are stunning, and if you are getting married here it is well worth setting aside a decent chunk of your day to move around the grounds from one stunning location to another.

The Treehouse interior is visually amazing, with large wooden beams, a roaring fire(!), twinkling fairy lights and lots of other quirky, rustic details. There are challenges, though. There are a number of different lights sources; tungsten lights, window light, naked flames, so setting a white balance and getting the correct colours in camera is very tough. The Treehouse is cramped, with narrow walkways and tables hidden away in nooks and crannies. If you are close to maximum capacity there is not much space to move or get a good view during the ceremony, for example, and your guests might not have a view of the top table for the speeches.

Alnwick Garden Treehouse Interior


  • Genuinely unique venue - where else can you get married in one of the largest treehouses in the UK or have a water cascade timed to your own music?
  • Visually stunning venue for wedding photography.


  • Treehouse interior is small so only suited to more intimate weddings.
  • Lots of outdoor elements means you could be affected by bad weather more than some other wedding venues.
