It's in Leicestershire!
The VT database is wrong......Market Harborough is most definitely in Leicestershire, although very near the border with Northamptonshire. I suspect the database works on the UK postcode system, which itself does not always tally with county boundaries. I'll let them know......
Anyway, Market Harborough. Not somewhere I regularly visit, but I thought a brief exploration would assuage my Saturday boredom.
It's a classic small English market town (though the market...livestock..is long gone, of course). It's not a particularly old town....it only grew up in the middle of the twelfth century, specifically to cater for the trade in wool (south Leicestershire was particularly good sheep country). Consequently there is nothing truly ancient to see. There are, however, some good examples of Georgian (and later) architecture, and one or two typical large brick factories of late Victorian (and later) times.
In effect, Market Harborough is one of England's first 'new towns'. The land alongside the main route was divided up into 'tofts' (around 48 yards in depth) quite deliberately to provide 'business opportunities'. for newcomers.
St Dionysius church (the steeple was considered by Pevsner to be particularly beautiful) dates from the 14th century, but its interior has little sense of age (imo). It has wooden galleries at the side of the nave, which is unusual in an English church, and a couple of reasonably of stone carved heads by the entrance, but that's about it.
The Old Grammar School was built in 1614, on wooden 'stilts', quite deliberately 'to keep the market people dry in time of foul weather'. which was considerate of the owner, one Robert Smyth. The brick part was added in 1868. Of course, it is no longer a school....
In more recent years a fast train service to London has meant that Market Harbororough has become a feasible and desirable commuter town. You and I might consider a 1.5 hour daily journey to work a dreadful idea, but many don't. The cost of property in London is horrendous, and many feel that a better 'quality of life' is obtainable for their families in other parts of England. Those areas nearest to London have long been very expensive so the coming of faster train services has meant more and more people commuting to London from much further away.
As a result, house prices in Market Harborough and the immediate area are extremely high....far higher than in other parts of Leicestershire (except for the city, which is itself commutable to London). The locals have to move out, and the incomers move in.......with their 4x4s, and their fast cars, and their desire for labels and luxury.
So Market Harborough has a wide range of small specialist shops (clothes, delicatessens and so on) as well as the usual chains (including M&S Food)and is very obviously a most 'comfortable' place to live.
Worth a brief visit if you are in the area, and probably a good base for exploring if you are staying for a while.
