CREATE TABLE table_16677738_1 (without_the_walls INT, within_the_walls INT)

When within the walls is larger than 56174.0 what is the lowest amount without the walls?
SELECT MIN(without_the_walls) FROM table_16677738_1 WHERE within_the_walls > 56174.0
SELECT MIN("without_the_walls") FROM "table_16677738_1" WHERE "within_the_walls" > 56174.0
