I was Pilot Monitoring. First Officer was Pilot flying. We were executing a Visual Approach backed up with the GPS. We were cleared to land on the left downwind leg and started the descent while turning base to cross the Final Approach Fix at 2;300 feet when the Tower gave us a low altitude alert. The airplane also gave us an obstacle warning. We were aware of the obstacle and did not think it was a factor as we were turning base and had situational awareness regarding the airport and terrane. We did not check with the Tower for the Minimum Vectoring Altitude (MVA); which should have been the case. We climbed to the MVA to intercept the final approach course and landed safely. In the future; when cleared for an approach; I will be sure to request the Minimum Vectoring Altitude if not given.
