Narrative:

After gear retraction the amber gear door light remained illuminated. Complied with QRH procedure and airspeed restrs. Called back to the flight attendants to see if they felt any unusual vibration or sounds in the wing area of the mid cabin. They reported a slight vibration just aft of the wing. We continued to ZZZ. When the gear was selected down; we had 3 green but the gear door open light was still on. We then complied with QRH procedures to include the gear door position check. We concluded that looking out the main landing gear visual position periscope may give us information on the position of the gear doors. The first officer went back and looked out the periscope and said that it looked like the gear doors were open. I then declared an emergency and informed approach that we would have to stop on the runway and have the gear pinned and the main landing gear doors secured. We then complied with the remainder of QRH if gear door is open procedure. Landed and came to a stop straight ahead. Maintenance secured the doors with ropes and pinned the gear.
