Bank of Oldtown
After the Rogare Bank collapsed in 136 AC, Lotho Rogare was taken up by Lady Samantha Tarly, paramour and step-mother of Lord Lyonel Hightower. House Hightower had not entrusted its gold to the bank, and remained one of the wealthiest houses of Westeros. Lady Samantha wished to learn how to invest better, and founded the Bank of Oldtown, which made House Hightower even richer.
