Abstract	This paper describes the design concept of the LHCb Hadron Calorimeter Prototype and it's construction experience. In total 6 modules with different internal structure have been assembled and tested on the X7 SPS beam-line during last three years. Various optics components, PMT's and digitizing electronics have been tested with the HCAL prototype. A calibration system with radiactive source and pulsing LED have been checked and accepted for further implementation. Several computer controlled sub-systems were developed to make the beam-test measurements precise and reliable. The constructed prototype showed a good performance and lead to the final design of the LHCb HCAL detector.
