The civic body plans to introduce sound and light show, supported by laser display, of important historical events which shaped the city in the last three centuries.

According to sources in the civic body, the 30-minute bilingual show will comprise audio, video and laser show, by which the White House (Ripon Building) will narrate the historical importance of the erstwhile Madras step by step, laced with unique anecdotes.

It would be an outdoor show and it would also be held on the corridors of the Ripon Building, which once bustled with British men for many decades. It would narrate history using specially designed lights and sound effects.

The whole thing has been designed on the lines of the one at Madurai Tirumalai Naicker Mahal, which showcases to tourists the history of the architecturally rich hall.

Tender for appointing a consulting agency has been already called for and it will be opened by August-end.

Once the preliminary works are completed, the project might take off within nine months at the lawns of the historical building, a senior official told Express.
