Wales
Starlings swirl under the pier at dusk, a cliff railway climbs, the national library watches.
On winter evenings starlings gather over the seafront in their thousands, wheeling as one before they drop to roost under the pier. Aberystwyth is a Victorian resort, a university town and, since UNESCO said so, Wales's first City of Literature, sitting on a bay where dolphins pass in early summer.
The promenade runs the whole front from the ruined castle to Constitution Hill, and the tradition on reaching the far end is to kick the low railing before turning back. From there the Cliff Railway, opened in 1896 and the longest in Britain, climbs to the world's largest camera obscura, a darkened room that projects a thousand square miles of coast and mountain onto a table, and to a café with the bay below. The Royal Pier, the oldest in Wales, is where the starlings roost between autumn and early spring, the murmuration building over the water before the birds drop under the deck. On the hill the National Library of Wales keeps the nation's books, including the smallest book in the world, beside the Arts Centre on the university campus. The town eats well for its size, from Ultracomida's Spanish-Welsh tapas and cheese counter to seafront hotels serving modern Welsh food, and the Vale of Rheidol steam railway leaves from beside the station for Devil's Bridge; it is a town for the edges of the year, when the students are in and the starlings are home.
