How does the poet use symbolism in the poem, To Penshurst?

In the poem, Penshurst becomes a symbol of the Sidneys and their involvement in English society. The speaker makes the argument at the beginning and end of the poem that, while other houses may have more elaborate structures and decor, Penshurst has a strong and admirable foundation that has lasted much longer than any others. He begins the poem by announcing the elements that do not exist at Penshurst, including "marble," "polished pillars," and "roof of gold" (2-3). Instead, Penshurst is an "ancient pile," a description that underscores the longevity of the home and therefore the continued influence of the Sidney family in English culture (5). Penshurst is figured as a more natural and organic addition to the landscape, one that fosters harmony and happiness throughout its surroundings. When the speaker says "Thou hast thy walks for health, as well as sport," he suggests that Penshurst represents endurance and longevity rather than simply showmanship (9). In his comparison of Penshurst to other large and impressive structures, Jonson effectively praises the Sidney family for their established position in English society and suggests that they are a natural part of the nation's structure and success.
