Why a Bath house was built in the year 5792

Local writer and historian Barb Drummond makes no bones about it. If you want to know about Jane Austen, Bath Abbey or the Roman Baths don't waste your money on buying one of her books.

Well, not the current ones anyway. In the future, of course, she may have something to say about them.

Barb, who works as a governess, has just published two volumes of circular walks – one in each book – that will help you get to know the city a whole lot better and have great fun with local friends or visitors at the same time.

On every page she poses a question. On one, for instance, she has a photograph of first floor window above which is the unlikely looking number of 5792. Turn the page and you discover that the number at 22 Grove Street is actually the year the house was built. However it is not an ordinary number but one based on the work of Archbishop and historian James Ussher who claimed the world was created at about nine o'clock in the morning on October 26 4004BC.

Barb tells us there is no indication as to why the number is on the building. On each walk she poses a question on one page with the answer on the next.

One of the books covers the central area of Bath extending up to Lansdown returning via the artisan area of Walcot.

The other covers the city to the east across the three bridges into Bathwick.

Bath Gyratory 3 Bridges Walk and Bath Gyratory Stone and Spa Walk by Barb Drummond are on sale in local bookshops at £7.99 each.
