LONDON, Sep. 6 (Xinhua) -- Seed Cathedral, the pavilion of the United Kingdom at Shanghai World Expo, will be under spotlights once again as the UK National Pavilion Day is due on Wednesday there.

The UK pavilion, themed "Building on the Past, Shaping Our future," features a display of various plant seeds instead of those old-time industrial glories hosted at Crystal Palace in London.

The structure, emphasizing seeds and nature, is widely recognized as a herald of emerging green tides which will surely surge in the future.

The Crystal Palace was built to host the Great Exhibition of Works of Industry of all Nations held in London in 1851, which is now recognized as the very first World Expo.

The dazzling differences between the two buildings not only mirror the changes of the architecture, but also the historical transformation of the world.

As the sole pavilion to host the Great Exhibition at Hyde Park in 1851,

the Crystal Palace accommodated more than 100,000 items on display, which was highlighted by industrial products, like engines, cranes, mills ..., all of which represented the most advanced technology at that time.
