The clock at City Hall is running again after thousands of pounds were spent to get it fixed.

It had been out of action since the first weekend of 2011, when the hands came to a halt at 10.30.

At first, council bosses thought the cold weather had led to the lubricant in the timepiece freezing, but specialists who studied the mechanism uncovered major problems.

That means the clock will need to be completely stripped down and rebuilt at a cost of �13.000.

Specialist Norwich-based company Michlmayr Clock & Watchmakers started the work last month. The hands were hoisted back into place this week.

The clock has had its fair share of problems, stopping completely around New Year in 2010, when the mechanism froze. In 2005 it stopped working just months after thousands were spent fixing it.
