Where does Pepys go to get a better view of the great fire?

In his diary, Samuel Pepys mentions climbing to the top of a nearby church tower, specifically St. Paul's Cathedral, to get a better view of the Great Fire of London in 1666. From this vantage point, he was able to observe the extent of the fire and its devastation across the city. His descriptions provide a vivid account of the chaos and destruction caused by the blaze.
