Thanks for your responses, but I don't think we've got the answer yet. It's some distance north of the city centre -- some miles. It bears a remarkable resemblance to the Gherkin but has square panels rather than diamond shapes, and without the helter-skelter appearance. I was travelling by ship to Barcelona Forum 2004, so it's between that site and the city. I think I know all the Gaudi sites and I'm sure it's not inspired by him, it's far too recent and geometric and unlike anything he has done. What I was interested in is whether this building inspired the Gherkin or vice versa.
