Beaumaris

A moated castle at one edge, a Victorian pier at the other, and Georgian streets in between, all of it flat, and all of it walkable in an afternoon.

01The town

Castle, streets and Strait in one compact town

Beaumaris runs along the shore of the Menai Strait in one flat line. The castle sits at the eastern edge of the town, Castle Street leads away from it through the centre, and the Green opens onto the waterfront with the pier reaching out from it. Everything in this guide lies on that one axis.

Why it matters

The castle draws people, but it is the smallest part of what Beaumaris kept. A 1614 courthouse and an 1829 gaol still stand as museums a few streets away, and the pier and the Green finish the same short walk. The castle is one stop of several here, not the whole reason to come.

Character

A working county town

Beaumaris is lived in year-round, with independent shops, cafés, homes and public spaces mixed through the visitor town.

Pace

Flat, end to end

There is no hill in Beaumaris. Park once and the whole visit is on foot; the only real decision is how long you spend inside the gaol and the courthouse.

Landscape

The Strait at its doorstep

The waterfront opens straight across the Strait to the mountains of Eryri, with the tide running hard through the channel below the pier.

Best for

A castle town with more than a castle

Best for anyone who wants several genuinely different historic buildings in one visit, and for a half-day on Anglesey that faces the mountains rather than the open sea.

Seven sights: a moated castle, a Georgian street, a Victorian pier, an open waterfront, a 14th-century parish church, and a separately-run gaol and courthouse. No restaurants, pubs or shops are listed here; see Local life for the town’s everyday character.

03Story

A planned town, still keeping its shape

Beaumaris (Welsh Biwmares) takes its name from the Norman-French beaux marais, “fair marsh.” The town was planned around a castle in 1295, and every layer since has been built inside that same plan.

  1. A marsh on the Strait, before the town

    People used this shore for fishing, trade and safe passage across the Menai Strait for centuries before 1295, the tides and the crossing that still define the town today.

  2. The planned castle-town, 1295

    Edward I’s last Welsh castle was built here from 1295, and a chartered town laid out beside it; the earlier Welsh community at Llanfaes was cleared to make room. The street pattern and the moated walls both still trace that plan.

  3. Anglesey’s county town, 1300s–1600s

    As a chartered borough Beaumaris held Anglesey’s courts; the 1614 courthouse (one of the older surviving courthouses in Britain) served as an assize court into the 1970s.

  4. Gaol, and a pier built for the steamers

    The 1829 gaol closed as a working prison after barely fifty years, so it was never modernised. The pier opened in 1846 and was extended in 1895 to draw the Liverpool pleasure steamers, the waterfront’s Victorian high-water mark.

  5. Museum and visitor town, today

    The gaol has been a museum since 1974; the castle joined Cadw’s UNESCO World Heritage Site with Edward I’s other Gwynedd castles; the pier was rebuilt in 2011–12. A working town underneath all of it.

The castle came first, and the town was planned around it. Five centuries later the courthouse and the gaol are what is left of running that town.

Local life & everyday character

A resident town by the water

Beaumaris is compact, but it is not only a heritage stop. Everyday life gathers along Castle Street, the Green and the waterfront, among cafés, pubs, shops, benches and the pier.

Visitors share these spaces with people who live here year-round. The front becomes busiest in fine weather and summer; outside that, the town feels quieter rather than closed.

Local tip

Puffin Island lies offshore and can be seen from the Green on a clear day. For a closer view, Starida’s wildlife cruises leave from the pier between April and October. The island itself is a nature reserve.

The working spine

Independent shops, cafés and pubs sit among Georgian and Victorian frontages. This is the part of Beaumaris people use every day, not simply somewhere visitors pass through.

The social front

Benches, the open view across the Strait and the pier make this the natural place to pause. In fine weather it becomes the town’s busiest shared space.

Life beyond the visitor season

Life beyond the visitor season · Beaumaris
Year-round town

Museums and cruises are seasonal, but the town itself is not. Residents, shops, pubs and local services keep Beaumaris functioning through the quieter months.

Town rhythm

Morning
Nothing ticketed opens before mid-morning. Until then the Green, the front and Castle Street are the whole of Beaumaris.
Through the day
Castle, gaol, courthouse and the Puffin Island boats all run at once. Fine weather pulls everyone onto the front; Castle Street stays the practical centre.
Evening & off-season
The ticketed interiors finish before the town does, and the Puffin Island boats stop for the winter. What is left is the front, the Strait and the light on the water.

The town in one walk

Beaumaris unfolds within a few streets.

Start in the centre and the town reveals itself naturally, through stone, open water and the everyday life between them.

Getting here

By car

The A545 from Menai Bridge is the road in, and it ends at Beaumaris rather than continuing east. Three pay-and-display car parks: by the castle, on the green, and at Canolfan Beaumaris on the west side.

Open The Green car park in Maps

By bus

Route 58 (Arriva) links Beaumaris with Bangor via Menai Bridge, calling on Castle Street. Nearest railway is Bangor, across the Strait. Check the current service before travelling.

Parking

Three car parks within walking distance of Castle Street: the county council’s by the castle, the town council’s on the green, and pay-and-display at Canolfan Beaumaris.
