Monument to stubbornness

I just read in "THE ROUGH GUIDE TO LONDON" about an architectural oddity that must be one of the great monument's to man's stubbornness.
Located along MILE END ROAD is a former department store -- a neoclassical building topped by a central domed tower built by THOMAS WICKHAM.
The perfect facade is interrupted, however, by a small, two-story shop that once housed a Jewish watchmaker named SPIEGELHALTER.
Spiegelhalter and Wickham were in dispute, so the latter -- a Gentile -- was forced to build his department store around the existing watchmaker's shop.
Brilliant!
