Take the high-speed rail and enter Paris from London in 2 hours. I bought a day subway ticket to check in to major attractions in Paris (thanks to the end of the strike). In the morning, the Eiffel Tower in the sun, then to the Arc de Triomphe, board the 284-step spiral staircase to the sightseeing platform in more than four minutes. Tour through the town hall, the memory of the appearance history - Notre Dame Paris (2019.4.15 partially burned, under maintenance).
