Geography Caernarfon is situated on the southern bank of the Menai Strait facing the Isle of Anglesey. It is situated south-west of Bangor, north of Porthmadog and approximately west of Llanberis and Snowdonia National Park. The mouth of the River Seiont is in the town, creating a natural harbour where it flows into the Menai Strait. Caernarfon Castle stands at the mouth of the river. The A487 passes directly through Caernarfon, with Bangor to the north and Porthmadog to the south. As the crow flies, the summit of Snowdon lies a little over to the southeast of the town centre. Economy Caernarfon's historical prominence and landmarks have made it a major tourist centre. As a result, many of the local businesses cater for the tourist trade. Caernarfon has numerous guest houses, inns and pubs, hotels, restaurants and shops. The majority of shops in the town are located either in the centre of town around Pool Street and Castle Square (Y Maes), on Doc Fictoria (Victoria Dock) or in Cei Llechi (Slate Quay). A number of shops are also located within the Town Walls. The majority of the retail and residential section of Doc Fictoria was opened in 2008. The retail and residential section of Doc Fictoria is built directly beside a Blue Flag beach marina. It contains numerous homes, bars and bistros, cafés and restaurants, an award-winning arts centre, a maritime museum and a range of shops and stores. Pool Street and Castle Square contain a number of large, national retail shops and smaller independent stores. Pool Street is pedestrianised and serves as the town's main shopping street. Castle Square, commonly referred to as the 'Maes' by both Welsh and English speakers, is the market square of the town. A market is held every Saturday throughout the year and also on Mondays in the summer. The square was revamped at a cost of £2.4 million in 2009. However, since its revamp the square has caused controversy due to traffic and parking difficulties. During the revamp, it was decided to remove barriers between traffic and pedestrians creating a 'shared space', to force drivers to be more considerate of pedestrians and other vehicles. This is the first use of this kind of arrangement in Wales, but it has been described by councillor Bob Anderson as being 'too ambiguous' for road users. Another controversy caused by the revamp of the Maes was that
