The present invention relates to a rainwater gutter for mounting on a building to collect rainwater from the roof. It is shaped similar to a letter S. The rainwater flows from the roof covering onto the top section of the S shaped curved element, where, due to the contour of the gutter and surface tension will flow down from the upper curved section into the cylindrical section via the opening formed by the bottom section of the S returning to terminate as an open end close to the top section. The small opening also emits daylight thus reducing the possibility of vegetation growing in the gutter. This will reduce expensive and dangerous maintenance of eave gutters. Because the water gathered from the eave of the roof is cleaner it would reduce filtration costs for rainwater harvesting. The gutter can be formed in plastic, aluminium, copper or zinc.
