Pop down to Camden Market in north London and you'll probably find somewhere you can buy spanners and knives... but you'll also find them at the bottom of its famous canal. These were just some of the items discovered this week when Camden Lock was drained for maintenance as part of a £45million countrywide project to keep the country's canal system in good working order. And the many tourists and students who visit the area this weekend are in for a treat as they will get the chance to venture to the bottom of the drained chamber of the Regent's Canal. As part of the £130,000 refurbishment work at the site - also known as Hampstead Road Lock - engineers are replacing both sets of lock gates, as well as carrying out brickwork repairs, repointing and timberwork.

The bottom set of lock gates are being replaced as they are old and worn, having been there for 25 years . The locks were constructed between 1818 and 1820 by James Morgan. It is the only twin-lock remaining on the canal. The current locks are Grade II-listed and replaced an innovative, but unsuccessful, lock system designed by William Congreve to try to conserve water. The lock is to the west of the Camden High Street road bridge. The yard and former warehouses, an area known as Camden Lock, are on the north side of the canal, at the junction with Chalk Farm Road. This area is adjacent to a canal basin and holds Camden Lock Market, one of the group of markets known as Camden Market. Many of the projects are carried out during winter to minimise the impact on waterway users. Richard .

As one of the most popular free attractions in London, the Camden Lock area will no doubt have heavy footfall tomorrow and Sunday, especially in the run-up to Christmas. The event is expected to be very popular and entry to the locks will be limited. Therefore, you will be required to book onto a tour when you arrive, and will be allocated on a first come, first serve basis. Graham Smith, construction supervisor at the site, said: 'We're replacing the bottom set of lock gates on lock 1 bay. It's old and worn, and has been . there 25 years. They leak and need to retain water. 'We're drilling so that we can take out the drop pot, which is like the hinge for a door. It  takes the weight of the water, thousands of tonnes of it.
