adminThe Jubilee, District and Circle lines stop at Westminster. The way to get there in the smallest number of stops is to take the Victoria line Southbound at King’s Cross St Pancras, from there it is 3 stops to Green Park, change there to the Jubilee line Southbound and Westminster is the next stop.

Just a point of interest – until just over 10 years ago the Jubilee line didn’t go past Charing Cross so Westminster station as it is now is a very recent construction. It’s quite a sight to behold as you come off the Jubilee line there… The whole station had to be rebuilt in connection with the construction of Portcullis House above it and basically what was done was to excavate a massive box under the building, lined with concrete and braced by steel poles, which you will see as you come up to the surface from the Jubilee line. The project had a very real risk of making Big Ben fall over (it’s just across the road) so care was taken to stop that by injections of concrete grout under Big Ben as the building works was going on. It won several architectural awards. I have to change trains there to get to work 5 days a week and I still find it impressive.

adminItalian TORRE PENDENTE DI PISA, medieval structure in Pisa, Italy, that is famous for the settling of its foundation, causing it to lean 17 feet from the perpendicular. The bell tower, begun in 1174 as the third and final structure of the city’s cathedral complex, was designed to stand 185 feet high and was constructed of white marble. Three of its eight stories were completed when the uneven settling of the building’s foundation in the soft ground became noticeable.

Bonnano Pisano, the engineer in charge, sought to compensate for the lean by making the new stories slightly taller on the short side, but the extra masonry caused the structure to sink still further. Work was suspended several times as engineers sought solutions, but the tower was ultimately topped out in the 14th century, still leaning.

In modern times the foundations have been strengthened by the injection of cement grouting, but in the late 20th century the structure was still in danger of collapse, and various schemes were being considered to save it.
