Walk north from the station up High Street and you cross the River Witham at High Bridge — a twelfth-century bridge rebuilt in the sixteenth, still carrying half-timbered shops, still pedestrianised, still leaking traffic onto the river it was supposed to span. North of the bridge the street is flat and pleasant, then it isn't. The lane narrows into The Strait, then Steep Hill, then Castle Hill, climbing roughly two hundred feet over a quarter of a mile. There is a handrail in places. Locals talk about it with the resigned humour of people who use it twice a day. The reward is that Lincoln preserved a Norman merchant's house on the way up — the Jew's House, late twelfth-century Romanesque, now a restaurant — and a second one, Norman House, which may have belonged to Aaron the Lincolnshire financier. Aaron lent money to abbeys across England in the 1100s. He was Jewish; the buildings of his community were seized in the antisemitic violence of that century. Lincoln's medieval prosperity owes more to its Jewish merchants than the city has always been willing to acknowledge.

At the top of Steep Hill the crossroads opens up. To your right is Exchequer Gate, the fourteenth-century gatehouse into the cathedral precinct — tenants of church lands once came here to pay rent on a chequered cloth, which is how the English government department got its name. Beyond it rises Lincoln Cathedral itself, three towers, west front carved within an inch of its life, one of the four surviving original copies of Magna Carta still kept inside. To your left is Lincoln Castle, Norman, intact, walkable around the walls, with a Victorian prison chapel in which inmates sat in coffin-like wooden boxes so they could not see each other. Between cathedral and castle runs Bailgate, where the road still traces the line of Ermine Street, the Roman road north, and where circles of stones set in the modern tarmac mark the foundations of Roman columns. Walk to the end of Bailgate and you pass through Newport Arch, the third-century north gate of Roman Lindum — still a working road arch, still carrying traffic, the oldest in Britain that does.

The upper town has the cathedral-adjacent restaurants you would expect, and a few that are better than that. Brown's Pie Shop on Steep Hill is the heritage choice — proper Lincolnshire pies, including the local speciality of haslet. The Wig and Mitre is a smart pub-restaurant a few doors up, named for the legal and ecclesiastical professions both within shouting distance. Slow Rise does very good pizza. The Cheese Society on St Martin's Lane is a working cheese shop with a small cafe attached, and a knowledgeable counter on which Lincolnshire Poacher (a hard, sharp regional cheese worth carrying home) is usually available. For a drink with a view, the Magna Carta pub sits right on the castle's east wall. For something quieter, the small bars around Bailgate trade on the cobbles. Down by the river, Brayford Pool — the inland marina the Romans used as a port — is now lined with chain restaurants and a couple of music venues; useful for cheap food and the university crowd, less useful for atmosphere.

Lincoln is two hours from London King's Cross on LNER, every two hours, via Peterborough, Grantham, and Newark Northgate. From the north you change at Newark off the East Coast Main Line. From Manchester or Sheffield, take Northern services via Worksop and Retford. The railway station and the bus station sit across the street from each other at the foot of the hill — convenient if your luggage is small. By road, the A1 passes Lincoln at a polite distance (Newark, twenty miles west), which is exactly why the medieval centre never got redeveloped. Once in town, walk. The medieval spine cannot accept anything bigger than a hand-cart. A summer sightseeing bus and the Walk & Ride loop service link the cathedral, castle, and lower town if the climb defeats you. Don't bring a car into the upper town unless you have committed to a multi-storey somewhere — the medieval streets are not for cars, and the council enforces that.

Once you have done Lincoln itself — and the cathedral, castle, library, bishop's palace, Greyfriars, Guildhall, and High Bridge will take you a comfortable two days — the surrounding county opens up. The International Bomber Command Centre on Canwick Hill is two miles south, free to walk around, sobering. The Lincolnshire Wolds roll east into chalk country. The old RAF airfields — Waddington still active with surveillance aircraft, Coningsby with Typhoons and the Battle of Britain Memorial Flight, Scampton (closed in 2022) where the Dambusters trained — cluster within twenty miles. Lincolnshire's flat land and abundance of WWII airfields was not an accident: the bombers needed long runways and short range to Germany. The shape of the modern landscape, viewed from the cathedral tower, still carries that history.
