The Senedd (Welsh Parliament) Travel Guide

The Senedd — a completely transparent glass殿堂 on the Cardiff Bay waterfront, officially opened on St David's Day 2006 by Queen Elizabeth II, designed by Pritzker Prize winner Richard Rogers (architect of London's Lloyd's Building and Paris's Pompidou Centre). The 5,308-square-metre building rests on a Welsh slate plinth with a Canadian western red cedar roof and a full glass façade symbolising democratic transparency. Geothermal wells, biomass boilers and rainwater harvesting systems reduce energy consumption by 30-50% compared to similar buildings. Here, 60 Members of the Senedd debate legislation, and the public can observe for free, join free guided tours, and enjoy panoramic Cardiff Bay views from the Oriel Café — one of the world's most environmentally friendly parliament buildings and the beating heart of Welsh democracy.

Highlights

Take Baycar Route 6 from Cardiff city centre or walk along the Cardiff Bay waterfront for about 20 minutes, passing the Wales Millennium Centre and Pierhead Building — the Senedd's glass façade already gleams in the sunlight. Airport-style security screening awaits at the entrance (allow 15 minutes), then collect tour information at Y Neuadd (Reception Hall) or download the free Senedd App. Join a free guided tour (or self-guided audio tour) up to Yr Oriel (Public Hall) on the first floor, looking down through the glass floor at the full circular debating chamber below — 60 Members' Welsh oak desks arranged in concentric circles, with Alexander Beleschenko's "Heart of Wales" glass fibre optic sculpture glowing softly at the centre. If visiting on a Tuesday or Wednesday afternoon, enter the public gallery to observe a Plenary session for free, experiencing the unique atmosphere of bilingual Welsh and English debate. Examine The Funnel — a tree-like wooden structure suspended from the roof, drawing natural light into the chamber while serving as a ventilation system. Descend to see the committee rooms' glass bridge corridor and Danny Lane's "The Assembly Field" glass sculpture, then finish at the Oriel Café with a Welsh coffee and freshly baked Welsh cake, gazing across Cardiff Bay through floor-to-ceiling glass.

Attractions
Y Siambr Debating Chamber & Public Gallery
Y Siambr (meaning "chamber") is the heart of the building — a circular debating hall where 60 Members of the Senedd (MS) sit around handcrafted Welsh oak desks arranged in concentric circles. At the centre stands Swansea artist Alexander Beleschenko's "Heart of Wales" glass fibre optic sculpture, whose fibre optic dots symbolise ideas converging and radiating from the people of Wales. Above, The Funnel-shaped wooden structure descends from the roof, functioning as both a light well and acoustic device. The public gallery encircles the debating chamber on the upper level, with 128 seats (including 12 wheelchair spaces) — free to access during Tuesday and Wednesday afternoon Plenary sessions. This is one of the world's most transparent parliamentary experiences, with the public literally seated above democracy in action. Debates are conducted bilingually in Welsh and English, with simultaneous interpretation available.
The Funnel Skylight & Glass Façade
The Senedd's most striking visual feature — The Funnel, a tree-like mega-structure crafted from Canadian western red cedar, suspended from the roof above the debating chamber. Its glass skylight draws in natural light, which is evenly distributed throughout the space via reflection off the funnel's inner surface, requiring almost no artificial lighting during the day. The Funnel also forms the core of an intelligent ventilation system: an automatically rotating cowl adjusts exhaust according to wind direction, working with automatically opening insulating glass windows to maintain constant temperature and humidity year-round without air conditioning. The entire building exterior is a fully transparent glass curtain wall, symbolising democratic transparency — passers-by on the waterfront can see directly into the debating chamber. The glass façade reflects Cardiff Bay's waters, changing colour throughout the day and night — a classic example of Richard Rogers' high-tech aesthetic of "expressing the building's structure externally."
Yr Oriel Public Hall & Senedd Café
Yr Oriel (meaning "gallery/hall") is the open public space on the first floor of the Senedd, extending around the base of The Funnel and offering 360-degree panoramic views of Cardiff Bay — floor-to-ceiling glass walls facing the bay waters on one side and the Millennium Centre and Pierhead Building on the other. This space houses free exhibition areas that rotate year-round, showcasing Welsh history, community stories and contemporary art. The Senedd Café sits to one side of the hall, serving hot drinks, cold meals, cakes and desserts — the signature afternoon tea combo with Welsh cake is a highlight, with affordable prices (coffee £2-3, cake £2-4). Sitting on a high stool at the café, sipping coffee while overlooking the debating chamber's glass roof and bay yachts, offers Cardiff Bay's most unique "political viewpoint." The hall also features an official shop selling Welsh crafts and books.
Y Neuadd Reception Hall, Committee Rooms & Free Guided Tours
Y Neuadd (meaning "hall") is the first public space after entering the Senedd, featuring a large slate and glass reception desk, building information displays and security screening lanes. From here, stairs and lifts lead up to Yr Oriel, with a staircase to the left leading to the glass bridge connecting the Committee Rooms — three committee rooms each seating 24-34 members, with double-glazed glass walls facing the internal courtyard for natural light. The public can observe committee inquiries for free from the public gallery on the bridge. Free Guided Tours depart from Y Neuadd, led by knowledgeable guides lasting approximately 45-60 minutes, covering architectural design concepts, sustainability systems, Welsh devolution history and democratic mechanisms. Maximum 40 people per group; advance booking via the website is recommended. Additionally, Danny Lane's glass sculpture "The Assembly Field" is located on the ground outside the southwest entrance, refracting rainbow-like light in the sun — a popular photo spot.
Slate Plinth, Pierhead Building & Cardiff Bay Waterfront Walkway
The Senedd's plinth is constructed from approximately 1,000 tonnes of Welsh slate from Blaenau Ffestiniog, rising in stepped tiers from Cardiff Bay's waters, symbolising democracy emerging from the people. Hidden within the slate plinth are the building's "private spaces" — Members' offices, technical equipment and mechanical systems — creating a deliberate contrast with the transparent public spaces above. Adjacent to the plinth stands the Pierhead Building, a Grade I listed Gothic Revival building completed in 1897, now also part of the parliamentary estate, housing free exhibitions (dock history, workers' stories, parliament design exhibitions etc.) — a natural continuation after visiting the Senedd. The waterfront walkway between the two buildings offers the best vantage point for photographing the Senedd's full panorama — especially at sunset when the glass façade reflects golden light interweaving with the bay waters. Richard Harris's sculpture "The Meeting Place on the Plinth" along the walkway is another photo hotspot.
